Mathematical Facts
Convert grain to stone with the formula below. st ≈ gr × 0.0000102040816327. 1 gr ≈ 0.00006479891 kg; 1 st ≈ 6.35029318 kg The grain, symbol gr, is a defined mass unit of 64.79891 milligrams. It is not a count of seeds and is not the gram, symbol g. A stone is a mass unit of 14 avoirdupois pounds. The result here is decimal stone, not a separate stone-and-pound pair.
Why This Conversion Matters
This comparison translates a defined grain mass into another notation, or back again. It does not convert a count of individual grains or seeds. Exact unit relationships: 1 gr = 64.79891 mg; 1 st = 14 lb. The calculator uses the full stored factor and rounds displayed results to 12 significant digits. Display precision is not a guarantee of measurement accuracy.
Real-World Examples
Interpreting the grain mass unit
The grain, symbol gr, is a defined mass unit of 64.79891 milligrams. It is not a count of seeds and is not the gram, symbol g. This comparison translates a defined grain mass into another notation, or back again. It does not convert a count of individual grains or seeds. The examples below are illustrative recorded masses, not standard product sizes or prescribed quantities.
Examples:
- Mass explicitly labeled in grains: 24 gr ≈ 0.000244897959184 st
- Mass explicitly labeled in grains: 480 gr ≈ 0.00489795918367 st
Pro Tips:
- ✓Confirm “grain” as the intended unit and use 64.79891 mg per gr; use a measured total mass for a collection of seeds.

Common Mistakes to Avoid
Reading gr as gram, or treating each seed as one grain unit
One grain is 0.06479891 g, not 1 g. A seed’s actual mass is a measurement, not the definition of this unit.
✓ Confirm “grain” as the intended unit and use 64.79891 mg per gr; use a measured total mass for a collection of seeds. 24 gr ≈ 0.000244897959184 st.
Pro Tips
- ✓Read the full unit name when a record says gr; do not silently interpret it as g.
- ✓For mixed notation, multiply the fractional stone by 14: 2.5 st means 2 st 7 lb.
- ✓Confirm “grain” as the intended unit and use 64.79891 mg per gr; use a measured total mass for a collection of seeds.
