How it works

Choose a category (length, mass, volume, or temperature), select the units to convert between, and type a value — the converted result updates instantly as you type.

Tip

Use the swap button between the two unit selectors to quickly flip the conversion direction.

How accurate are the conversions?

All conversions use standard, precise conversion factors (e.g. exactly 1 mile = 1609.344 meters), so results are accurate to floating-point precision.
