Rounding and precision rules
- Convr calculates first and rounds the displayed result only once, at the final step.
- The default is a maximum of 6 decimal places; trailing zeros are removed.
- Very small values that would appear as zero, and values of 10¹² or more, use scientific notation.
- Display precision is not measurement uncertainty. For scientific, engineering, or regulated work, retain only the digits justified by the source measurement.
Practical context
Understanding this conversion
Kilograms are the standard unit for body mass in most countries. Stone remains familiar for personal weight in parts of the United Kingdom and Ireland, making this conversion useful for conversation and older records.
A decimal result can be converted to traditional stone-and-pounds notation: keep the whole stone and multiply the remaining fraction by 14 to find pounds.

st = kg × 0.157473
Calculations retain full precision and the result is rounded only for display.
Worked example
For 10 kg, the result is 1.57473 st. Substitute 10 kg into the formula to obtain 1.57473 st.
A numerical value expressed in stone is usually smaller than the same measurement expressed in kilogram, because 1 kg equals 0.157473 st.
