Ounce types: a quick clarification

Most everyday conversions use the avoirdupois ounce, which is what this calculator uses. In precious metals, you may see a troy ounce, which is different. If you are converting gold, silver, or similar materials, always confirm which ounce standard is required.

Tips for accurate conversions

1) Keep enough decimal places

For shopping and recipes, 2 to 3 decimals is usually enough. For technical work, use 4 to 8 decimals.

2) Round only at the end

If you chain multiple calculations, keep full precision until your final step to reduce rounding error.

3) Verify unit labels

Make sure the original number is in grams (g), not kilograms (kg), and that the output is ounces (oz), not pounds (lb).
