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
Long tons still appear in some British historical, naval, shipping, and industrial records. Metric tons are standard for modern international trade and scientific reporting.
The long ton is based on exactly 2,240 international pounds. Its metric-ton equivalent is slightly greater than one, so careful labeling prevents confusion with the US short ton.
