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.
Calculation
Carat to Metric ton formula
t = ct × 2e-7
Calculations retain full precision and the result is rounded only for display.
Worked example
For 10 ct, the result is 0.000002 t. Substitute 10 ct into the formula to obtain 0.000002 t.
A numerical value expressed in metric ton is usually smaller than the same measurement expressed in carat, because 1 ct equals 2e-7 t.
