How to Change KM to Miles on Apple Watch: A Small Business Guide

As a small business owner or entrepreneur, you may want to customize the unit of measurement on your Apple Watch. This guide will show you how to change from kilometers (KM) to miles on Apple Watch to best suit your business needs.

Why Switch Units for a Small Business?

There are several reasons a small business may want to change the distance units on their Apple Watches:

  • Expanding internationally – If your small business is going global, you‘ll need your Apple Watch to match local units of measurement. For example, switching to miles if entering a market like the US.
  • Training clients – Fitness coaches and personal trainers may want to track distances in miles when training US-based clients rather than KM.
  • Traveling for business – Frequently traveling entrepreneurs can change units when visiting countries that use different systems. Matching local preferences.
  • Converting existing data – Import/export businesses may want to convert data tracked in KM to miles when expanding into US markets.

According to recent surveys, around 25% of small businesses use wearable devices like Apple Watch. As a small business owner, customizing your Apple Watch‘s units of measurement can optimize operations and prevent confusion.

Changing Units in Health App

To change both your Apple Watch and iPhone Activity app:

  1. In the Health app on your iPhone, tap the Activity tab.
  2. Scroll down and select Walking + Running Distance.
  3. Tap Unit and choose miles or kilometers.

The Apple Watch Activity screens will also instantly update to the new unit. This impacts total distance tracking.

For a small business owner with multiple devices, phasing in this change over time allows for adaptation across the organization.

Switching Units in Workout App

To change just the Workout app unit on your Apple Watch:

  1. Open the Workout app on the Apple Watch.
  2. Start a run workout (indoor or outdoor).
  3. Swipe left and tap the three dots to open options.
  4. Choose Distance from the menu.
  5. Select Miles or KM.

The Apple Watch Workout app will now save your chosen unit for future workouts. This is helpful for small business owners who want to track runs in miles but keep other devices in KM.

Changing Default Region Settings

You can also change the system-wide default unit of measurement on all devices:

  1. Go to Settings > General on your iPhone.
  2. Tap Language & Region.
  3. Select Region.
  4. Choose a region that uses your preferred system. Such as United States for miles.

However, this will impact all apps using distance measurements. Be aware it may require restarting and some apps are slower to update than others.

As a small business owner, it‘s smart to gradually roll out major device changes to catch any unintended impacts early. Expect some transition time for your organization to fully adapt.

Limitations to Know

While Apple makes it easy to switch units, some limitations exist:

  • Non-Apple apps may not change instantly.
  • Watch apps like Maps may need restarts to reflect new units.
  • Frequently changing back and forth can require patience.

For a small business, allow time for tweaking the change if issues emerge. Communication and training for staff is also advised when altering systems company-wide.


With some strategic planning, a small business can successfully customize Apple Watch and iPhone distance units for their needs. Consider the change carefully, implement gradually, and communicate clearly.
