How to convert pounds to us tons (short)
1 pound is equal to 0.0005 us ton (short):
1 lb = (453.59237 g ÷ 907184.74 g) ust = 0.0005 ust
Each pound is defined as 453.59237 g and each us ton (short) as 907184.74 g, so one lb equals 453.59237 ÷ 907184.74 ust = 0.0005 ust.
Let w(lb) be the numeric value of the same mass measured in Pound (lb), and w(ust) the value in US Ton (Short) (ust). Then:
w(ust) = w(lb) × (453.59237 / 907184.74)
Equivalently, divide by how many lb fit into one ust (grams per ust divided by grams per lb):
w(ust) = w(lb) ÷ 2000
Or: us ton (short) = pound ÷ 2000
Examples
Example #1: Convert 20 lb to us ton (short)
20 lb = 20 lb × (453.59237/907184.74) ust = 0.01 ust
20 lb = 20 lb ÷ 2000 = 0.01 ust
Example #2: Convert 50 lb to us ton (short)
50 lb = 50 lb × (453.59237/907184.74) ust = 0.025 ust
50 lb = 50 lb ÷ 2000 = 0.025 ust
Summary
To convert Pound to US Ton (Short), multiply the value in lb by the ratio of grams per lb divided by grams per ust. Equivalently: value_ust = value_lb × (453.59237 / 907184.74). Numerically, 1 lb equals 0.0005 ust.
