Formula, accuracy & limitations
Target amount = entered amount × source-unit factor ÷ target-unit factor. Base-unit factors: kg = 1; lb = 0.45359237; st = 6.35029318; g = 0.001; oz = 0.028349523125.
This converts mass only; it does not recommend a body weight.
Calculations use your inputs. Main numeric values show up to six decimal places, percentages up to two, and chart labels up to four. Time results use hours, minutes and seconds. Very small nonzero values use scientific notation.
Read the measurement reference ↗Read mixed stones and pounds correctly
A stones field uses decimal stones, not a stones-and-pounds code. Eleven stone four pounds is 11 + 4/14 stones, not 11.4 stones. Use pounds if your original reading has mixed units to avoid this notation mistake.
