About Kilogram
The kilogram is the SI base unit of mass (defined via fundamental constants). Everyday metric weights and science use kilograms and grams.
About Stone
The stone is 14 pounds (UK and Ireland). It is often used for human body weight in those regions.
How to convert kilograms to stone
1 kilogram is equal to 0.15747304441777 stone:
1 kg = (1000 g ÷ 6350.29318 g) st = 0.15747304441777 st
Each kilogram is defined as 1000 g and each stone as 6350.29318 g, so one kg equals 1000 ÷ 6350.29318 st = 0.15747304441777 st.
Let w(kg) be the numeric value of the same mass measured in Kilogram (kg), and w(st) the value in Stone (st). Then:
w(st) = w(kg) × (1000 / 6350.29318)
Equivalently, divide by how many kg fit into one st (grams per st divided by grams per kg):
w(st) = w(kg) ÷ 6.35029318
Or: stone = kilogram ÷ 6.35029318
Examples
Example #1: Convert 20 kg to stone
20 kg = 20 kg × (1000/6350.29318) st = 3.1494608884 st
20 kg = 20 kg ÷ 6.35029318 = 3.1494608884 st
Example #2: Convert 50 kg to stone
50 kg = 50 kg × (1000/6350.29318) st = 7.8736522209 st
50 kg = 50 kg ÷ 6.35029318 = 7.8736522209 st
Summary
To convert Kilogram to Stone, multiply the value in kg by the ratio of grams per kg divided by grams per st. Equivalently: value_st = value_kg × (1000 / 6350.29318). Numerically, 1 kg equals 0.15747304441776971 st.
Relationship context
You are converting between metric (SI) (Kilograms) and imperial / UK (stone, long ton, pound, ounce) (Stone). Metric mass is decimal from the gram; US and imperial masses use pounds and ounces with fixed definitions relative to the kilogram. The numeric factor used here is 1.574730e-1.
