Unit converters

Switching between metric and imperial units is a daily task for travellers, cooks, students and anyone shopping abroad. These converters give exact results, show every related unit at once, and include reference tables for the most common conversions.

Imperial units are defined exactly in terms of metric ones (an inch is precisely 2.54 centimeters, and a pound is precisely 0.45359237 kilograms), so the factors used here are exact and only the displayed results are rounded.
