How to convert pounds to long tons (uk)
1 pound is equal to 0.00044642857143 long ton (uk):
1 lb = (453.59237 g ÷ 1016046.9088 g) lton = 0.00044642857143 lton
Each pound is defined as 453.59237 g and each long ton (uk) as 1016046.9088 g, so one lb equals 453.59237 ÷ 1016046.9088 lton = 0.00044642857143 lton.
Let w(lb) be the numeric value of the same mass measured in Pound (lb), and w(lton) the value in Long Ton (UK) (lton). Then:
w(lton) = w(lb) × (453.59237 / 1016046.9088)
Equivalently, divide by how many lb fit into one lton (grams per lton divided by grams per lb):
w(lton) = w(lb) ÷ 2240
Or: long ton (uk) = pound ÷ 2240
