You’ll also learn how to use the EufySecurity app—yes, that’s the right app—for managing your health devices. Along the way, we’ll share practical tips, troubleshooting advice, and answers to frequently asked questions.

By the end of this guide, you’ll be able to confidently switch your Eufy device to kilograms, ensure accurate readings, and keep your health data consistent across platforms. Let’s get started!

Why Change from Lb to Kg?

Before diving into the steps, it’s worth understanding why someone might want to switch from pounds to kilograms. While both units measure weight, kilograms are part of the metric system, which is used by most countries around the world. If you’re tracking fitness goals, following a diet plan, or monitoring medical conditions, using kilograms can offer better precision and alignment with global standards.

For example, many nutrition labels and fitness apps default to kilograms. If you’re using a Eufy scale alongside apps like Apple Health, Google Fit, or MyFitnessPal, switching to kg can help avoid confusion and manual conversions. Plus, kilograms allow for smaller, more granular increments—ideal for tracking gradual weight changes.

Additionally, if you’re sharing the scale with family members who prefer metric units, changing the setting ensures everyone gets readings in their preferred format. It’s a small change that makes a big difference in usability.

What You’ll Need

Before you begin, make sure you have the following:

• A Eufy smart scale or health device – Confirm your model supports metric units (most modern ones do).
• The EufySecurity app installed on your smartphone – Available for both iOS and Android.
• A stable Wi-Fi or Bluetooth connection – Required for syncing data and accessing settings.
• Your Eufy account login details – You’ll need to sign in to access device settings.
• A flat, hard surface for the scale – Ensures accurate measurements during setup.

Having these ready will make the process smoother and help avoid interruptions.

Step 1: Confirm Your Eufy Model Supports Kilograms

Not all Eufy devices support switching between units. While most modern smart scales do, some older or basic models may only display weight in pounds. To check:

Check the Product Manual or Packaging

Look for mentions of “metric units,” “kg/lb toggle,” or “unit selection” in the user manual. If you no longer have the manual, visit the official Eufy website and search for your model number (e.g., “Eufy Smart Scale C1 manual”).

Look at the Scale Display

Stand on the scale and observe the reading. If it shows “kg” or allows you to toggle between units using a button, your model likely supports kilograms. Some scales display both units briefly after stepping off.

Check the App Compatibility

Open the EufySecurity app and go to your device settings. If you see a “Unit” or “Measurement” option, your scale supports switching. If not, your model may be limited to pounds.

If your device doesn’t support kg, consider upgrading to a newer model like the Eufy Smart Scale P1, which offers full metric support and advanced health tracking.

Step 2: Download and Set Up the EufySecurity App

The EufySecurity app is the central hub for managing all Eufy devices, including smart scales. Even though it’s named for security products, it also handles health and wellness devices.

Download the App

Go to the Apple App Store (iOS) or Google Play Store (Android) and search for “EufySecurity.” Download and install the app. Make sure you’re getting the official app by Anker Innovations.

Create or Log In to Your Account

Open the app and sign in with your existing Eufy account. If you don’t have one, tap “Sign Up” and follow the prompts to create an account using your email address.

Add Your Scale to the App

If your scale isn’t already connected:

• Turn on the scale and ensure it’s in pairing mode (usually indicated by a blinking light).
• In the app, tap the “+” icon and select “Add Device.”
• Choose “Smart Scale” or “Health Device” from the list.
• Follow the on-screen instructions to connect via Bluetooth or Wi-Fi.

Once connected, your scale will appear in the app’s device list.

Step 3: Change the Unit from Lb to Kg in the App

Now for the main event: switching from pounds to kilograms.

Open the EufySecurity App

Launch the app and make sure you’re logged in. Tap on the “Devices” tab at the bottom of the screen.

Select Your Smart Scale

Find your scale in the list and tap on it to open the device dashboard. You should see options like “Weight History,” “Users,” and “Settings.”

Navigate to Settings

Look for a gear icon or “Settings” option—usually in the top-right corner. Tap it to access configuration options.

Find the Unit or Measurement Setting

Scroll through the settings menu until you see “Unit,” “Weight Unit,” or “Measurement System.” Tap on it.

Switch from Lb to Kg

You’ll see a toggle or dropdown menu with options like “Pounds (lb)” and “Kilograms (kg).” Select “Kilograms (kg).”

Save the Changes

Tap “Save” or “Confirm” to apply the new setting. The app may take a few seconds to sync with the scale.

Once saved, your scale will now display weight in kilograms. Step on it to confirm the change.

Step 4: Change the Unit Directly on the Scale (If Supported)

Some Eufy models allow you to switch units directly on the device, without using the app. This is useful if you don’t have your phone nearby.

Locate the Unit Button

Check the side or bottom of your scale for a small button labeled “Unit,” “Mode,” or “lb/kg.” On some models, this button is recessed and requires a paperclip to press.

Press and Hold the Button

Press and hold the unit button for 3–5 seconds. The display should flash or cycle through available units (e.g., lb → kg → st).

Release When Kilograms Appear

When “kg” appears on the screen, release the button. The scale will save the setting automatically.

Test the Change

Step on the scale to ensure it now shows weight in kilograms. If it reverts to pounds, repeat the process or use the app method instead.

Note: Not all Eufy scales have a physical unit button. If yours doesn’t, rely on the app method.

Step 5: Sync Your Data Across Devices

After changing the unit, it’s important to sync your data so other apps and devices reflect the correct measurements.

Open Your Health App

Launch apps like Apple Health, Google Fit, or MyFitnessPal. These often pull data from your Eufy scale.

Check Recent Weight Entries

Look at your latest weight log. If it still shows pounds, the sync may not have updated yet.

Force a Sync

In the EufySecurity app, go to your scale’s settings and tap “Sync Now” or “Refresh Data.” Wait a few moments, then check your health app again.

Adjust Historical Data (If Needed)

If past entries are in pounds, you may need to manually convert them or contact Eufy support for help. Unfortunately, the app doesn’t automatically convert historical data when you change units.

Keeping your data consistent ensures accurate progress tracking and avoids confusion.

Step 6: Calibrate Your Scale for Accuracy

Switching units doesn’t affect calibration, but it’s a good idea to verify your scale is still accurate—especially after changing settings.

Use a Known Weight

Place a dumbbell, bag of flour, or another object with a known weight (e.g., 5 kg) on the scale. Check if the reading matches.

Re-Calibrate if Necessary

If the reading is off, follow the calibration steps in the Eufy app:

• Go to your scale’s settings.
• Tap “Calibrate” or “Reset.”
• Follow the on-screen instructions (usually involves stepping on and off the scale).

Place on a Hard, Flat Surface

Always use your scale on tile, hardwood, or another hard surface. Carpets can cause inaccurate readings.

Regular calibration ensures your kg measurements are reliable.

Troubleshooting Common Issues

Sometimes, changing units doesn’t go as planned. Here’s how to fix common problems.

Unit Setting Won’t Save

If the scale keeps reverting to pounds:

• Restart the scale by removing and reinserting the batteries.
• Reconnect the scale to the app and try changing the unit again.
• Ensure the app is updated to the latest version.

App Doesn’t Show Unit Option

If you can’t find the unit setting in the app:

• Confirm your scale model supports metric units.
• Reinstall the EufySecurity app and log back in.
• Contact Eufy support for model-specific guidance.

Scale Shows Inconsistent Readings

If weights fluctuate or seem incorrect:

• Calibrate the scale as described above.
• Check for low battery—replace if needed.
• Ensure the scale is on a level surface.

Bluetooth or Wi-Fi Connection Issues

If the app can’t connect to the scale:

• Move closer to the scale.
• Turn off and on Bluetooth on your phone.
• Reset the scale’s network settings via the app.

Most issues can be resolved with these steps. If problems persist, visit the Eufy support page or contact customer service.

Tips for Using Your Eufy Scale in Kilograms

Now that your scale is set to kg, here are some tips to get the most out of it:

• Weigh yourself at the same time each day – Preferably in the morning, before eating or drinking, for consistent results.
• Use the app to track trends – The EufySecurity app shows weight history, body fat, muscle mass, and more in kg.
• Set goals in kilograms – Whether it’s losing 5 kg or gaining muscle, use kg for precise goal setting.
• Share with family safely – Add multiple user profiles in the app so everyone gets personalized kg readings.
• Keep the scale clean – Wipe the surface regularly to maintain accuracy and hygiene.

Using kilograms doesn’t just change the numbers—it can improve your overall health tracking experience.
