Rounded for display only; calculations retain full precision.
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
Kilograms are used internationally for mass, while ounces are common for smaller food, parcel, and retail quantities in US customary contexts.
This conversion uses the avoirdupois ounce. Precious metals may use troy ounces, which have a different mass and must not be substituted.
