How to convert stone to us tons (short)
1 stone is equal to 0.007 us ton (short):
1 st = (6350.29318 g ÷ 907184.74 g) ust = 0.007 ust
Each stone is defined as 6350.29318 g and each us ton (short) as 907184.74 g, so one st equals 6350.29318 ÷ 907184.74 ust = 0.007 ust.
Let w(st) be the numeric value of the same mass measured in Stone (st), and w(ust) the value in US Ton (Short) (ust). Then:
w(ust) = w(st) × (6350.29318 / 907184.74)
Equivalently, divide by how many st fit into one ust (grams per ust divided by grams per st):
w(ust) = w(st) ÷ 142.85714285714286
Or: us ton (short) = stone ÷ 142.85714285714286
Examples
Example #1: Convert 20 st to us ton (short)
20 st = 20 st × (6350.29318/907184.74) ust = 0.14 ust
20 st = 20 st ÷ 142.85714285714286 = 0.14 ust
Example #2: Convert 50 st to us ton (short)
50 st = 50 st × (6350.29318/907184.74) ust = 0.35 ust
50 st = 50 st ÷ 142.85714285714286 = 0.35 ust
Summary
To convert Stone to US Ton (Short), multiply the value in st by the ratio of grams per st divided by grams per ust. Equivalently: value_ust = value_st × (6350.29318 / 907184.74). Numerically, 1 st equals 0.006999999999999999 ust.
Relationship context
You are converting between imperial / UK (stone, long ton, pound, ounce) (Stone) and US customary (short ton) (US Tons (Short)). 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 7.000000e-3.
