Unit Converters

Unit mistakes are expensive — a recipe in ounces, a part spec in millimeters, a torque figure in newton-meters when your wrench reads foot-pounds. These converters cover the pairs people actually need, with exact conversion factors rather than rounded folklore, and they convert as you type in either direction. Each page also explains where the units come from and when precision matters, so you can sanity-check the answer instead of trusting a black box.
