About this calculator

India measures groceries in kg but body weight discussions with American friends drift into pounds (and UK stones!). One kilogram equals exactly 2.20462 pounds — the definition has been atomic-constant since the 2019 SI redefinition.

Formula

result = value × (from-unit factor ÷ to-unit factor), where factors are relative to the SI base unit.

Frequently Asked Questions

How exact are these conversions?

Factors use internationally agreed definitions — an inch is exactly 2.54 cm since 1959, a pound exactly 0.45359237 kg since 1959.

Why can't I enter zero or negatives?

Physical quantities here are magnitudes; negative lengths/weights are meaningless in this context.
