Units and unit conversion

Workout Writer supports both metric and imperial units, and can convert values when needed.

That matters most when you open or share a workout written in a different unit system than your own.

Choose your unit system

When you first open the app, it will choose the most likely option based on your phone's settings, but this can easily be changed.

Go to:

Settings → Units

Then select:

In the Units screen, you can configure how converted pace/speed values are rounded.

Examples:

Use the rounding controls to choose precision, for example:

You can also set default pace/speed ranges so exact inputs become more practical target bands.

For example:

Workout Writer can automatically convert distance values from the opposite unit system.

Example:

When using metric, convert imperial text like feet, yards, and miles into metric distances.

You can also configure rounding separately for:

Example conversions:

If you share workouts with people using different units, enable conversion and choose rounding that matches your coaching style.
If you'd like to use mixed units e.g. you usually use miles, but use metres for the track, then disable distance conversion in Unit Settings.
For strict interval sessions, use tighter rounding.
For easy runs or long rides, broader rounding is often more readable.

The goal is not just mathematical accuracy. It is workouts that still read sensibly once they land on someone else's device.
