How to convert us tons (short) to carats
1 us ton (short) is equal to 4535923.69999999925494 carat:
1 ust = (907184.74 g ÷ 0.2 g) ct = 4535923.69999999925494 ct
Each us ton (short) is defined as 907184.74 g and each carat as 0.2 g, so one ust equals 907184.74 ÷ 0.2 ct = 4535923.69999999925494 ct.
Let w(ust) be the numeric value of the same mass measured in US Ton (Short) (ust), and w(ct) the value in Carat (ct). Then:
w(ct) = w(ust) × (907184.74 / 0.2)
Equivalently, divide by how many ust fit into one ct (grams per ct divided by grams per ust):
w(ct) = w(ust) ÷ 2.20462262e-7
Or: carat = us ton (short) ÷ 2.20462262e-7
Examples
Example #1: Convert 20 ust to carat
20 ust = 20 ust × (907184.74/0.2) ct = 90718474 ct
20 ust = 20 ust ÷ 2.20462262e-7 = 90718474 ct
Example #2: Convert 50 ust to carat
50 ust = 50 ust × (907184.74/0.2) ct = 226796185 ct
50 ust = 50 ust ÷ 2.20462262e-7 = 226796185 ct
Summary
To convert US Ton (Short) to Carat, multiply the value in ust by the ratio of grams per ust divided by grams per ct. Equivalently: value_ct = value_ust × (907184.74 / 0.2). Numerically, 1 ust equals 4535923.699999999 ct.
