How to convert stone to hundredweight (us)
1 stone is equal to 0.14 hundredweight (us):
1 st = (6350.29318 g ÷ 45359.237 g) cwt_us = 0.14 cwt_us
Each stone is defined as 6350.29318 g and each hundredweight (us) as 45359.237 g, so one st equals 6350.29318 ÷ 45359.237 cwt_us = 0.14 cwt_us.
Let w(st) be the numeric value of the same mass measured in Stone (st), and w(cwt_us) the value in Hundredweight (US) (cwt_us). Then:
w(cwt_us) = w(st) × (6350.29318 / 45359.237)
Equivalently, divide by how many st fit into one cwt_us (grams per cwt_us divided by grams per st):
w(cwt_us) = w(st) ÷ 7.14285714285714
Or: hundredweight (us) = stone ÷ 7.14285714285714
Examples
Example #1: Convert 20 st to hundredweight (us)
20 st = 20 st × (6350.29318/45359.237) cwt_us = 2.8 cwt_us
20 st = 20 st ÷ 7.14285714285714 = 2.8 cwt_us
Example #2: Convert 50 st to hundredweight (us)
50 st = 50 st × (6350.29318/45359.237) cwt_us = 7 cwt_us
50 st = 50 st ÷ 7.14285714285714 = 7 cwt_us
Summary
To convert Stone to Hundredweight (US), multiply the value in st by the ratio of grams per st divided by grams per cwt_us. Equivalently: value_cwt_us = value_st × (6350.29318 / 45359.237). Numerically, 1 st equals 0.13999999999999999 cwt_us.
