Units: metric and imperial

Setting your units

You choose metric or imperial when you sign up, and you can change it later in your profile settings. The preference is per person — your coach and each athlete can each view in whatever system they prefer.

If you sign up in imperial, the height and weight fields switch to ft / in and lb so you can enter what you actually know; the Grepiac converts and stores the metric value.

How values are shown

Grepiac stores everything in metric (kilometres, metres, kilograms, °C) and converts on the way out for imperial viewers:

• distances in mi, elevation in ft, weight in lb, height in ft′in″, temperature in °F;
• run/ride pace per mile, swim pace per 100 yd;
• speeds are shown in both systems on race reports, e.g. 32.0 km/h (19.9 mph).

Bucketed figures (for example swim-pace bands) are rounded to clean numbers in your unit, not raw-converted — so you see tidy ranges rather than long decimals.

Where it does and does not apply

The display layer follows the viewer everywhere it matters: the dashboards, activity pages, readiness and recap reports, and the in-browser calculators (which also pre-fill imperial input fields for imperial users). Internally everything stays metric, so switching your unit never changes any stored data — only how it is shown.
