Work out weight converter instantly with clear inputs, formula shown and shareable results.
Every mass unit is defined as a multiple of the kilogram, so this converter works in two steps: multiply the input by the source unit's factor to reach kilogram, then divide by the target unit's factor. That is why any pair in the list converts correctly without needing a separate formula for each combination.
Two-step conversion
result = value × factor(from) ÷ factor(to)
Base unit
base (kilogram) = value × factor(from)
With 10 units there would be 90 direct pairs to maintain. Routing through kilogram needs only one factor per unit and gives identical results.
Yes — the first is the unit your number is already in, the second is the unit you want. Swapping them inverts the result.
