Rounding and precision rules
- Convr calculates first and rounds the displayed result only once, at the final step.
- The default is a maximum of 6 decimal places; trailing zeros are removed.
- Very small values that would appear as zero, and values of 10¹² or more, use scientific notation.
- Display precision is not measurement uncertainty. For scientific, engineering, or regulated work, retain only the digits justified by the source measurement.
Practical context
Understanding this conversion
Grams are convenient for food, laboratory samples, small parcels, and metric product labels. Ounces commonly express similar quantities in United States recipes, packaging, and shipping.
The ounce on this page is the international avoirdupois ounce, equal to exactly 28.349523125 grams. Precious metals are usually quoted in troy ounces and must not be converted with this factor.
