About Stone
The stone is 14 pounds (UK and Ireland). It is often used for human body weight in those regions.
About Gram
The gram is one thousandth of a kilogram. Recipes, lab work, and small masses typically use grams.
How to convert stone to grams
1 stone is equal to 6350.29317999999967 gram:
1 st = (6350.29318 g ÷ 1 g) g = 6350.29317999999967 g
Each stone is defined as 6350.29318 g and each gram as 1 g, so one st equals 6350.29318 ÷ 1 g = 6350.29317999999967 g.
Let w(st) be the numeric value of the same mass measured in Stone (st), and w(g) the value in Gram (g). Then:
w(g) = w(st) × (6350.29318 / 1)
Equivalently, divide by how many st fit into one g (grams per g divided by grams per st):
w(g) = w(st) ÷ 0.00015747304442
Or: gram = stone ÷ 0.00015747304442
Examples
Example #1: Convert 20 st to gram
20 st = 20 st × (6350.29318/1) g = 127005.8636 g
20 st = 20 st ÷ 0.00015747304442 = 127005.8636 g
Example #2: Convert 50 st to gram
50 st = 50 st × (6350.29318/1) g = 317514.659 g
50 st = 50 st ÷ 0.00015747304442 = 317514.659 g
Summary
To convert Stone to Gram, multiply the value in st by the ratio of grams per st divided by grams per g. Equivalently: value_g = value_st × (6350.29318 / 1). Numerically, 1 st equals 6350.29318 g.
Relationship context
You are converting between imperial / UK (stone, long ton, pound, ounce) (Stone) and metric (SI) (Grams). 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 6.350293e+3.
