How to convert hundredweight (uk) to hundredweight (us)
1 hundredweight (uk) is equal to 1.12 hundredweight (us):
1 cwt_uk = (50802.34544 g ÷ 45359.237 g) cwt_us = 1.12 cwt_us
Each hundredweight (uk) is defined as 50802.34544 g and each hundredweight (us) as 45359.237 g, so one cwt_uk equals 50802.34544 ÷ 45359.237 cwt_us = 1.12 cwt_us.
Let w(cwt_uk) be the numeric value of the same mass measured in Hundredweight (UK) (cwt_uk), and w(cwt_us) the value in Hundredweight (US) (cwt_us). Then:
w(cwt_us) = w(cwt_uk) × (50802.34544 / 45359.237)
Equivalently, divide by how many cwt_uk fit into one cwt_us (grams per cwt_us divided by grams per cwt_uk):
w(cwt_us) = w(cwt_uk) ÷ 0.89285714285714
Or: hundredweight (us) = hundredweight (uk) ÷ 0.89285714285714
Examples
Example #1: Convert 20 cwt_uk to hundredweight (us)
20 cwt_uk = 20 cwt_uk × (50802.34544/45359.237) cwt_us = 22.4 cwt_us
20 cwt_uk = 20 cwt_uk ÷ 0.89285714285714 = 22.4 cwt_us
Example #2: Convert 50 cwt_uk to hundredweight (us)
50 cwt_uk = 50 cwt_uk × (50802.34544/45359.237) cwt_us = 56 cwt_us
50 cwt_uk = 50 cwt_uk ÷ 0.89285714285714 = 56 cwt_us
Summary
To convert Hundredweight (UK) to Hundredweight (US), multiply the value in cwt_uk by the ratio of grams per cwt_uk divided by grams per cwt_us. Equivalently: value_cwt_us = value_cwt_uk × (50802.34544 / 45359.237). Numerically, 1 cwt_uk equals 1.1199999999999999 cwt_us.
