The Pace Converter turns Value, From, To into Converted value, instantly and for free. For instance, with Value = 5, From = min/km and To = min/km it returns Converted value = 5.

How to use it

  1. Enter your values: Value, From, To.
  2. Read the result instantly: Converted value.

Frequently asked questions

How does the Pace Converter work?

It takes Value, From and To and derives Converted value from them. The calculation is live as you type, so the result updates on every change.

Which values does the calculator ask for?

3 values: Value, From and To. Nothing else is required — no account, no file upload.

What does a typical calculation look like?

With Value = 5, From = min/km and To = min/km, the calculator returns Converted value = 5. Those figures come from running this exact tool, so you can reproduce them by entering the same values.

How much does the result change with different inputs?

It moves a lot. Using Value = 10, From = min/mile and To = min/mile instead, Converted value goes from 5 to 10 — which is why it is worth testing a few scenarios rather than trusting a single figure.

Which “From” option should I choose?

You can pick between « min/km », « min/mile », « km/h » and « mph ». Each one changes what the calculator works out, so switch and compare — the default is « min/km ».

What does it give for smaller values?

Scaled down to Value = 2.5, From = min/km and To = min/km, Converted value comes out at 2.5. The relationship is worth checking at both ends before you rely on a single result.

When would I actually use this?

Preparing a race: the pace a target time needs, the splits to hold it, and the training zones that sit under it — on foot, and equally on a bike or in a pool, where the same session is measured in watts or in a hundred-metre split instead.

What is the most common mistake?

Scaling a time linearly to a longer distance. A marathon is not two half-marathons; race predictors use an exponent around 1.06 precisely because fatigue is not proportional.

What is the difference between the Pace Converter and the Pace Zone Calculator?

This one returns Converted value; the Pace Zone Calculator returns Result. That is the whole difference — open the one whose figure you need.

Is there a tool for the next step?

Triathlon Pace Calculator is the closest one after this: Swim, bike and run splits with per-segment pace and total time, with preset race distances.
