How to convert hundredweight (us) to hundredweight (uk)
1 hundredweight (us) is equal to 0.89285714285714 hundredweight (uk):
1 cwt_us = (45359.237 g ÷ 50802.34544 g) cwt_uk = 0.89285714285714 cwt_uk
Each hundredweight (us) is defined as 45359.237 g and each hundredweight (uk) as 50802.34544 g, so one cwt_us equals 45359.237 ÷ 50802.34544 cwt_uk = 0.89285714285714 cwt_uk.
Let w(cwt_us) be the numeric value of the same mass measured in Hundredweight (US) (cwt_us), and w(cwt_uk) the value in Hundredweight (UK) (cwt_uk). Then:
w(cwt_uk) = w(cwt_us) × (45359.237 / 50802.34544)
Equivalently, divide by how many cwt_us fit into one cwt_uk (grams per cwt_uk divided by grams per cwt_us):
w(cwt_uk) = w(cwt_us) ÷ 1.12
Or: hundredweight (uk) = hundredweight (us) ÷ 1.12
Examples
Example #1: Convert 20 cwt_us to hundredweight (uk)
20 cwt_us = 20 cwt_us × (45359.237/50802.34544) cwt_uk = 17.8571428571 cwt_uk
20 cwt_us = 20 cwt_us ÷ 1.12 = 17.8571428571 cwt_uk
Example #2: Convert 50 cwt_us to hundredweight (uk)
