This page splits a kilogram figure into whole stones and the pounds left over. The other page starts from the way people say a weight, stone plus pounds, and turns that into kilograms. Rounding the leftover pounds to the nearest pound is how most people say it. The pounds here are kept to two decimals so the split still adds back to the kilograms.

The factor is exact. The figure on screen is rounded for reading.

How to use it

  1. Enter the weight in kilograms.
  2. Read the whole stones and the pounds left over.
  3. Round the leftover pounds yourself if you want the way someone would say it aloud.

Splitting a kilogram figure

Divide the kilograms by 0.45359237 to get pounds, then take whole stones at 14 pounds each. The remainder is the leftover pounds. Seventy kilograms is 11 stone and about 0.3 pounds, which most people would call 11 stone.

The leftover is kept to two decimals so it still adds back to the kilograms you typed. Saying “11 stone 2” when the remainder was 1.6 pounds is a speech habit. The page shows the unrounded remainder and leaves that last step to you.

Why this is a separate page

The stones and pounds page starts from how a weight is spoken and produces a clinic-ready kilogram figure. This page starts from the clinic, the scales or a form already in kilograms, which is the usual Irish medical record, and produces the stone-and-pounds phrase.

The same pound is used for body weight and for a recipe. A stone is a body-weight unit in everyday UK and Irish speech. You will not see a stone of flour on a modern pack.
