How to convert hundredweight (uk) to long tons (uk)
1 hundredweight (uk) is equal to 0.05 long ton (uk):
1 cwt_uk = (50802.34544 g ÷ 1016046.9088 g) lton = 0.05 lton
Each hundredweight (uk) is defined as 50802.34544 g and each long ton (uk) as 1016046.9088 g, so one cwt_uk equals 50802.34544 ÷ 1016046.9088 lton = 0.05 lton.
Let w(cwt_uk) be the numeric value of the same mass measured in Hundredweight (UK) (cwt_uk), and w(lton) the value in Long Ton (UK) (lton). Then:
w(lton) = w(cwt_uk) × (50802.34544 / 1016046.9088)
Equivalently, divide by how many cwt_uk fit into one lton (grams per lton divided by grams per cwt_uk):
w(lton) = w(cwt_uk) ÷ 20
Or: long ton (uk) = hundredweight (uk) ÷ 20
Examples
Example #1: Convert 20 cwt_uk to long ton (uk)
20 cwt_uk = 20 cwt_uk × (50802.34544/1016046.9088) lton = 1 lton
20 cwt_uk = 20 cwt_uk ÷ 20 = 1 lton
Example #2: Convert 50 cwt_uk to long ton (uk)
50 cwt_uk = 50 cwt_uk × (50802.34544/1016046.9088) lton = 2.5 lton
50 cwt_uk = 50 cwt_uk ÷ 20 = 2.5 lton
Summary
To convert Hundredweight (UK) to Long Ton (UK), multiply the value in cwt_uk by the ratio of grams per cwt_uk divided by grams per lton. Equivalently: value_lton = value_cwt_uk × (50802.34544 / 1016046.9088). Numerically, 1 cwt_uk equals 0.049999999999999996 lton.
