About Pound

About Hundredweight (US)

How to convert pounds to hundredweight (us)
1 pound is equal to 0.01 hundredweight (us):
1 lb = (453.59237 g ÷ 45359.237 g) cwt_us = 0.01 cwt_us
Each pound is defined as 453.59237 g and each hundredweight (us) as 45359.237 g, so one lb equals 453.59237 ÷ 45359.237 cwt_us = 0.01 cwt_us.
Let w(lb) be the numeric value of the same mass measured in Pound (lb), and w(cwt_us) the value in Hundredweight (US) (cwt_us). Then:
w(cwt_us) = w(lb) × (453.59237 / 45359.237)
Equivalently, divide by how many lb fit into one cwt_us (grams per cwt_us divided by grams per lb):
w(cwt_us) = w(lb) ÷ 100
Or: hundredweight (us) = pound ÷ 100
Examples
Example #1: Convert 20 lb to hundredweight (us)
20 lb = 20 lb × (453.59237/45359.237) cwt_us = 0.2 cwt_us
20 lb = 20 lb ÷ 100 = 0.2 cwt_us
Example #2: Convert 50 lb to hundredweight (us)
50 lb = 50 lb × (453.59237/45359.237) cwt_us = 0.5 cwt_us
50 lb = 50 lb ÷ 100 = 0.5 cwt_us
Summary
To convert Pound to Hundredweight (US), multiply the value in lb by the ratio of grams per lb divided by grams per cwt_us. Equivalently: value_cwt_us = value_lb × (453.59237 / 45359.237). Numerically, 1 lb equals 0.01 cwt_us.
