How to convert carats to us tons (short)
1 carat is equal to 2.20462262e-7 us ton (short):
1 ct = (0.2 g ÷ 907184.74 g) ust = 2.20462262e-7 ust
Each carat is defined as 0.2 g and each us ton (short) as 907184.74 g, so one ct equals 0.2 ÷ 907184.74 ust = 2.20462262e-7 ust.
Let w(ct) be the numeric value of the same mass measured in Carat (ct), and w(ust) the value in US Ton (Short) (ust). Then:
w(ust) = w(ct) × (0.2 / 907184.74)
Equivalently, divide by how many ct fit into one ust (grams per ust divided by grams per ct):
w(ust) = w(ct) ÷ 4535923.69999999925494
Or: us ton (short) = carat ÷ 4535923.69999999925494
Examples
Example #1: Convert 20 ct to us ton (short)
20 ct = 20 ct × (0.2/907184.74) ust = 0.0000044092 ust
20 ct = 20 ct ÷ 4535923.69999999925494 = 0.0000044092 ust
Example #2: Convert 50 ct to us ton (short)
50 ct = 50 ct × (0.2/907184.74) ust = 0.0000110231 ust
50 ct = 50 ct ÷ 4535923.69999999925494 = 0.0000110231 ust
Summary
To convert Carat to US Ton (Short), multiply the value in ct by the ratio of grams per ct divided by grams per ust. Equivalently: value_ust = value_ct × (0.2 / 907184.74). Numerically, 1 ct equals 2.204622621848776e-7 ust.
Relationship context
You are converting between metric (SI) (Carats) and US customary (short ton) (US Tons (Short)). 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 2.204623e-7.
