About Grain
The grain is 1/7000 of a pound (exactly 64.79891 mg). It is used in ballistics, pharmacy, and precious-metal contexts.
About Metric Ton
The metric ton (tonne) is 1,000 kilograms or one million grams. It is standard for freight, agriculture, and industrial mass in most metric countries.
How to convert grains to metric tons
1 grain is equal to 6.47989100e-8 metric ton:
1 gr = (0.06479891 g ÷ 1000000 g) t = 6.47989100e-8 t
Each grain is defined as 0.06479891 g and each metric ton as 1000000 g, so one gr equals 0.06479891 ÷ 1000000 t = 6.47989100e-8 t.
Let w(gr) be the numeric value of the same mass measured in Grain (gr), and w(t) the value in Metric Ton (t). Then:
w(t) = w(gr) × (0.06479891 / 1000000)
Equivalently, divide by how many gr fit into one t (grams per t divided by grams per gr):
w(t) = w(gr) ÷ 1.54323584e+7
Or: metric ton = grain ÷ 1.54323584e+7
Examples
Example #1: Convert 20 gr to metric ton
20 gr = 20 gr × (0.06479891/1000000) t = 0.000001296 t
20 gr = 20 gr ÷ 1.54323584e+7 = 0.000001296 t
Example #2: Convert 50 gr to metric ton
50 gr = 50 gr × (0.06479891/1000000) t = 0.0000032399 t
50 gr = 50 gr ÷ 1.54323584e+7 = 0.0000032399 t
Summary
To convert Grain to Metric Ton, multiply the value in gr by the ratio of grams per gr divided by grams per t. Equivalently: value_t = value_gr × (0.06479891 / 1000000). Numerically, 1 gr equals 6.479891e-8 t.
Relationship context
You are converting between imperial / UK (stone, long ton, pound, ounce) (Grains) and metric (SI) (Metric Tons). 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 6.479891e-8.
