LBS to KG Converter: Pounds to Kilograms

Pounds to kilograms is the reverse of the classic luggage-and-gym conversion. Ten pounds is about four and a half kilograms. The factor is exact by definition, so the converter's answer is limited only by display rounding.

How the conversion works

Multiply the pound value by exactly 0.45359237. The widget below starts at 10 lb; change it to anything — a suitcase, a parcel, a barbell — and press Convert.

Watch the direction

Multiplying converts pounds to kilograms; dividing converts kilograms to pounds. Mixing the two directions is the most common mistake, so the tile grid under the result shows every unit at once for comparison.

Keep in mind

  • Mass only — not force, and not fluid or troy ounces.
  • Keep the precision of your input in mind: a scale reading of 10 lb supports about two or three significant figures.
