Weight & Mass converter
Kilograms, pounds, stones, ounces, tonnes and troy weights.
Weight conversions trip people up because three different 'tons' and two different 'ounces' are in daily use. This converter keeps them straight: metric mass, avoirdupois weight, troy weight for precious metals, and the stone still used across the UK and Ireland.
