How to convert long tons (uk) to us tons (short)
1 long ton (uk) is equal to 1.12 us ton (short):
1 lton = (1016046.9088 g ÷ 907184.74 g) ust = 1.12 ust
Each long ton (uk) is defined as 1016046.9088 g and each us ton (short) as 907184.74 g, so one lton equals 1016046.9088 ÷ 907184.74 ust = 1.12 ust.
Let w(lton) be the numeric value of the same mass measured in Long Ton (UK) (lton), and w(ust) the value in US Ton (Short) (ust). Then:
w(ust) = w(lton) × (1016046.9088 / 907184.74)
Equivalently, divide by how many lton fit into one ust (grams per ust divided by grams per lton):
w(ust) = w(lton) ÷ 0.89285714285714
Or: us ton (short) = long ton (uk) ÷ 0.89285714285714
Examples
Example #1: Convert 20 lton to us ton (short)
20 lton = 20 lton × (1016046.9088/907184.74) ust = 22.4 ust
20 lton = 20 lton ÷ 0.89285714285714 = 22.4 ust
Example #2: Convert 50 lton to us ton (short)
50 lton = 50 lton × (1016046.9088/907184.74) ust = 56 ust
50 lton = 50 lton ÷ 0.89285714285714 = 56 ust
Summary
To convert Long Ton (UK) to US Ton (Short), multiply the value in lton by the ratio of grams per lton divided by grams per ust. Equivalently: value_ust = value_lton × (1016046.9088 / 907184.74). Numerically, 1 lton equals 1.1199999999999999 ust.
