How to convert pounds to metric tons
1 pound is equal to 0.00045359237 metric ton:
1 lb = (453.59237 g ÷ 1000000 g) t = 0.00045359237 t
Each pound is defined as 453.59237 g and each metric ton as 1000000 g, so one lb equals 453.59237 ÷ 1000000 t = 0.00045359237 t.
Let w(lb) be the numeric value of the same mass measured in Pound (lb), and w(t) the value in Metric Ton (t). Then:
w(t) = w(lb) × (453.59237 / 1000000)
Equivalently, divide by how many lb fit into one t (grams per t divided by grams per lb):
w(t) = w(lb) ÷ 2204.62262184877591
Or: metric ton = pound ÷ 2204.62262184877591
Examples
Example #1: Convert 20 lb to metric ton
20 lb = 20 lb × (453.59237/1000000) t = 0.0090718474 t
20 lb = 20 lb ÷ 2204.62262184877591 = 0.0090718474 t
Example #2: Convert 50 lb to metric ton
50 lb = 50 lb × (453.59237/1000000) t = 0.0226796185 t
50 lb = 50 lb ÷ 2204.62262184877591 = 0.0226796185 t
Summary
To convert Pound to Metric Ton, multiply the value in lb by the ratio of grams per lb divided by grams per t. Equivalently: value_t = value_lb × (453.59237 / 1000000). Numerically, 1 lb equals 0.00045359237000000004 t.
Relationship context
You are converting between imperial / UK (stone, long ton, pound, ounce) (Pounds) and metric (SI) (Metric Tons). Metric mass is decimal from the gram; US and imperial masses use pounds and ounces with fixed definitions relative to the kilogram. The numeric factor used here is 4.535924e-4.
