About

TreadmillPace is a free tool site for one job: converting treadmill belt speed (mph or km/h) to running pace (min/mile or min/km) — and the reverse.

No accounts. No app install. Math runs in your browser so it works on weak gym Wi‑Fi.

What we offer

• Treadmill pace calculator — bidirectional conversion + optional incline estimate
• Treadmill pace chart — printable lookup table

Accuracy

Core speed ↔ pace conversion uses the standard relationship pace = 60 ÷ speed (with matching units). Pace is shown to the second; speed to 0.1.

Incline “flat-equivalent” pace is an estimate for training context only. It is not a lab measurement and is not medical advice.

What we don’t do

We don’t sell coaching, store workouts, or claim AI-perfect physiology models. If you need a custom number, use the calculator; if you need a rail sheet, print the chart.
