ABOUT THIS TOOL

Free Weight Converter — Convert Kg, Lb, Oz, Grams & Stone

Convert kilograms, grams, milligrams, pounds, ounces, stone and metric tonnes with a live all-unit comparison matrix.

Common mass conversion relationships

Toolmera converts every supported unit through kilograms as a shared base, then calculates the selected target and the full comparison matrix.

The pound and ounce entries use international avoirdupois definitions; troy ounces for precious metals are intentionally not mixed into this general weight converter.
