How it works

A handy converter for the units that come up most — distance and weight — across metric and imperial systems. It converts only within a type, so it won’t let you turn kilograms into miles.

Frequently asked questions

Why can’t I convert length to weight?

They measure different physical quantities, so there’s no fixed relationship between them. The converter keeps conversions within a type — length to length, weight to weight — to stay meaningful.
