How to convert long tons (uk) to carats
1 long ton (uk) is equal to 5080234.54399999976158 carat:
1 lton = (1016046.9088 g ÷ 0.2 g) ct = 5080234.54399999976158 ct
Each long ton (uk) is defined as 1016046.9088 g and each carat as 0.2 g, so one lton equals 1016046.9088 ÷ 0.2 ct = 5080234.54399999976158 ct.
Let w(lton) be the numeric value of the same mass measured in Long Ton (UK) (lton), and w(ct) the value in Carat (ct). Then:
w(ct) = w(lton) × (1016046.9088 / 0.2)
Equivalently, divide by how many lton fit into one ct (grams per ct divided by grams per lton):
w(ct) = w(lton) ÷ 1.96841306e-7
Or: carat = long ton (uk) ÷ 1.96841306e-7
Examples
Example #1: Convert 20 lton to carat
20 lton = 20 lton × (1016046.9088/0.2) ct = 101604690.8799999952 ct
20 lton = 20 lton ÷ 1.96841306e-7 = 101604690.8799999952 ct
Example #2: Convert 50 lton to carat
50 lton = 50 lton × (1016046.9088/0.2) ct = 254011727.1999999881 ct
50 lton = 50 lton ÷ 1.96841306e-7 = 254011727.1999999881 ct
Summary
To convert Long Ton (UK) to Carat, multiply the value in lton by the ratio of grams per lton divided by grams per ct. Equivalently: value_ct = value_lton × (1016046.9088 / 0.2). Numerically, 1 lton equals 5080234.544 ct.
