How many ounces are in a stone?

There are 224 ounces in one stone (1 stone = 14 pounds, 1 pound = 16 ounces, so 14 × 16 = 224 oz).

What is the formula to convert ounces to stones?

Divide the ounce value by 224. For example, 448 oz ÷ 224 = 2 stones exactly. For the remainder, take the leftover after whole stones, divide by 16 for pounds, and the rest stays as ounces.

Is the stone used outside the UK?

The stone is primarily used in the UK and Ireland for body weight. Most other countries use kilograms. The stone is not part of the metric system.

Can I convert decimal ounces?

Yes. Enter any decimal value (e.g. 156.5 oz) and the converter handles the fractional part, displaying a decimal remainder in the ounces field.

How accurate is the conversion?

The conversion is exact — 1 stone is exactly 224 ounces by definition. Results are displayed to two decimal places where needed.
