Mathematical Facts
Convert stone to ounce with the formula below. oz ≈ st × 224. 1 st ≈ 6.35029318 kg; 1 oz ≈ 0.028349523125 kg A stone is a mass unit of 14 avoirdupois pounds. The result here is decimal stone, not a separate stone-and-pound pair. The ounce here is an avoirdupois mass ounce, useful for interpreting a small-part or ingredient mass. A fluid ounce measures volume instead.
Why This Conversion Matters
This pair is useful when a mass record uses stone and another record uses a different unit. Convert mixed stone-and-pound notation before entering a decimal value. Exact unit relationships: 1 st = 14 lb; 16 oz = 1 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
Decimal and mixed stone notation
A stone is a mass unit of 14 avoirdupois pounds. The result here is decimal stone, not a separate stone-and-pound pair. This pair is useful when a mass record uses stone and another record uses a different unit. Convert mixed stone-and-pound notation before entering a decimal value. The examples below are illustrative recorded masses, not standard product sizes or prescribed quantities.
Examples:
- Mass written in decimal stone: 2.5 st ≈ 560 oz
- Mass written in decimal stone: 7.25 st ≈ 1,624 oz
Pro Tips:
- ✓For input, add pounds ÷ 14 to whole stones. For output, multiply the fractional stone by 14 to recover pounds.
Quick Reference Table
| stones | ounces |
|---|---|
| 1 st | 224 oz |
| 2 st | 448 oz |
| 5 st | 1,120 oz |

Common Mistakes to Avoid
Reading 2.5 st as 2 st 5 lb
Half a stone is 7 lb, so 2.5 st equals 35 lb; 2 st 5 lb equals 33 lb. The notation error changes the mass by 2 lb.
✓ For input, add pounds ÷ 14 to whole stones. For output, multiply the fractional stone by 14 to recover pounds. 2.5 st ≈ 560 oz.
Pro Tips
- ✓For mixed notation, multiply the fractional stone by 14: 2.5 st means 2 st 7 lb.
- ✓Keep oz, oz t and fl oz distinct: they identify an avoirdupois mass, a troy mass and a volume.
- ✓For input, add pounds ÷ 14 to whole stones. For output, multiply the fractional stone by 14 to recover pounds.
