- Mechanical horsepower and metric horsepower are explicitly distinguished because they use different documented conversion constants.
- Energy represents the amount of energy, whereas Power represents the rate of energy transfer.
- The calculator uses documented conversion constants without rounding intermediate calculation values. Display formatting may shorten the visible result.
- Negative power values are rejected as invalid.
