How to convert hundredweight (us) to long tons (uk)
1 hundredweight (us) is equal to 0.04464285714286 long ton (uk):
1 cwt_us = (45359.237 g ÷ 1016046.9088 g) lton = 0.04464285714286 lton
Each hundredweight (us) is defined as 45359.237 g and each long ton (uk) as 1016046.9088 g, so one cwt_us equals 45359.237 ÷ 1016046.9088 lton = 0.04464285714286 lton.
Let w(cwt_us) be the numeric value of the same mass measured in Hundredweight (US) (cwt_us), and w(lton) the value in Long Ton (UK) (lton). Then:
w(lton) = w(cwt_us) × (45359.237 / 1016046.9088)
Equivalently, divide by how many cwt_us fit into one lton (grams per lton divided by grams per cwt_us):
w(lton) = w(cwt_us) ÷ 22.4
Or: long ton (uk) = hundredweight (us) ÷ 22.4
Examples
Example #1: Convert 20 cwt_us to long ton (uk)
20 cwt_us = 20 cwt_us × (45359.237/1016046.9088) lton = 0.8928571429 lton
20 cwt_us = 20 cwt_us ÷ 22.4 = 0.8928571429 lton
Example #2: Convert 50 cwt_us to long ton (uk)
50 cwt_us = 50 cwt_us × (45359.237/1016046.9088) lton = 2.2321428571 lton
50 cwt_us = 50 cwt_us ÷ 22.4 = 2.2321428571 lton
Summary
To convert Hundredweight (US) to Long Ton (UK), multiply the value in cwt_us by the ratio of grams per cwt_us divided by grams per lton. Equivalently: value_lton = value_cwt_us × (45359.237 / 1016046.9088). Numerically, 1 cwt_us equals 0.044642857142857144 lton.
