Frequently asked questions
Which mass units are included?
Milligram, gram, kilogram, metric ton, ounce, pound, and stone. The pound uses its exact 0.45359237 kg definition, so recipe and shipping figures line up with official tables.
Is this the same as converting weight to force?
No. These are mass units, not newtons, so gravity is not part of the calculation. Everything is worked out in your browser with a fixed factor table and nothing is uploaded.
