How it works
Enter a value in any unit field and the tool instantly calculates the equivalent in every other unit using precise conversion factors. For example, 1 kilogram equals exactly 2.20462 pounds, 35.274 ounces, 1000 grams, or 15,432.36 grains. The Mass table feature displays a full cross-reference so you can see all relationships in one view. Because processing happens locally in JavaScript, conversions are both fast and completely private.
