About Stone
The stone is 14 pounds (UK and Ireland). It is often used for human body weight in those regions.
About Metric Ton
The metric ton (tonne) is 1,000 kilograms or one million grams. It is standard for freight, agriculture, and industrial mass in most metric countries.
How to convert stone to metric tons
1 stone is equal to 0.00635029318 metric ton:
1 st = (6350.29318 g ÷ 1000000 g) t = 0.00635029318 t
Each stone is defined as 6350.29318 g and each metric ton as 1000000 g, so one st equals 6350.29318 ÷ 1000000 t = 0.00635029318 t.
Let w(st) be the numeric value of the same mass measured in Stone (st), and w(t) the value in Metric Ton (t). Then:
w(t) = w(st) × (6350.29318 / 1000000)
Equivalently, divide by how many st fit into one t (grams per t divided by grams per st):
w(t) = w(st) ÷ 157.4730444177697
Or: metric ton = stone ÷ 157.4730444177697
Examples
Example #1: Convert 20 st to metric ton
20 st = 20 st × (6350.29318/1000000) t = 0.1270058636 t
20 st = 20 st ÷ 157.4730444177697 = 0.1270058636 t
Example #2: Convert 50 st to metric ton
50 st = 50 st × (6350.29318/1000000) t = 0.317514659 t
50 st = 50 st ÷ 157.4730444177697 = 0.317514659 t
Summary
To convert Stone to Metric Ton, multiply the value in st by the ratio of grams per st divided by grams per t. Equivalently: value_t = value_st × (6350.29318 / 1000000). Numerically, 1 st equals 0.00635029318 t.
Relationship context
You are converting between imperial / UK (stone, long ton, pound, ounce) (Stone) and metric (SI) (Metric Tons). 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.
