How to convert us tons (short) to long tons (uk)
1 us ton (short) is equal to 0.89285714285714 long ton (uk):
1 ust = (907184.74 g ÷ 1016046.9088 g) lton = 0.89285714285714 lton
Each us ton (short) is defined as 907184.74 g and each long ton (uk) as 1016046.9088 g, so one ust equals 907184.74 ÷ 1016046.9088 lton = 0.89285714285714 lton.
Let w(ust) be the numeric value of the same mass measured in US Ton (Short) (ust), and w(lton) the value in Long Ton (UK) (lton). Then:
w(lton) = w(ust) × (907184.74 / 1016046.9088)
Equivalently, divide by how many ust fit into one lton (grams per lton divided by grams per ust):
w(lton) = w(ust) ÷ 1.12
Or: long ton (uk) = us ton (short) ÷ 1.12
Examples
Example #1: Convert 20 ust to long ton (uk)
20 ust = 20 ust × (907184.74/1016046.9088) lton = 17.8571428571 lton
20 ust = 20 ust ÷ 1.12 = 17.8571428571 lton
Example #2: Convert 50 ust to long ton (uk)
50 ust = 50 ust × (907184.74/1016046.9088) lton = 44.6428571429 lton
50 ust = 50 ust ÷ 1.12 = 44.6428571429 lton
Summary
To convert US Ton (Short) to Long Ton (UK), multiply the value in ust by the ratio of grams per ust divided by grams per lton. Equivalently: value_lton = value_ust × (907184.74 / 1016046.9088). Numerically, 1 ust equals 0.8928571428571429 lton.
