How to convert hundredweight (uk) to stone
1 hundredweight (uk) is equal to 8 stone:
1 cwt_uk = (50802.34544 g ÷ 6350.29318 g) st = 8 st
Each hundredweight (uk) is defined as 50802.34544 g and each stone as 6350.29318 g, so one cwt_uk equals 50802.34544 ÷ 6350.29318 st = 8 st.
Let w(cwt_uk) be the numeric value of the same mass measured in Hundredweight (UK) (cwt_uk), and w(st) the value in Stone (st). Then:
w(st) = w(cwt_uk) × (50802.34544 / 6350.29318)
Equivalently, divide by how many cwt_uk fit into one st (grams per st divided by grams per cwt_uk):
w(st) = w(cwt_uk) ÷ 0.125
Or: stone = hundredweight (uk) ÷ 0.125
Examples
Example #1: Convert 20 cwt_uk to stone
20 cwt_uk = 20 cwt_uk × (50802.34544/6350.29318) st = 160 st
20 cwt_uk = 20 cwt_uk ÷ 0.125 = 160 st
Example #2: Convert 50 cwt_uk to stone
50 cwt_uk = 50 cwt_uk × (50802.34544/6350.29318) st = 400 st
50 cwt_uk = 50 cwt_uk ÷ 0.125 = 400 st
Summary
To convert Hundredweight (UK) to Stone, multiply the value in cwt_uk by the ratio of grams per cwt_uk divided by grams per st. Equivalently: value_st = value_cwt_uk × (50802.34544 / 6350.29318). Numerically, 1 cwt_uk equals 8 st.
