A terawatt is an SI unit of power equal to one trillion watts (10^12 watts), used for expressing very large power rates such as those of national or planetary scale energy flows.

What does horsepower measure?

Horsepower is a non-SI power unit representing the rate of doing work, commonly used to rate engines and machinery; the mechanical version equals about 745.7 watts.

Can I use this tool for everyday engine power conversions?

This converter is best suited for very large power conversions since terawatt scales are vastly greater than typical engine outputs. For small engines, other tools may be more appropriate.

Browser-based and easy to use with no installation required
Provides results in commonly recognized mechanical horsepower units
Supports conversions useful in energy, automotive, and astrophysical contexts
Displays clear conversion steps and example calculations

Examples

0.5 Terawatt converts to approximately 670,511,044.8 Horsepower
2 Terawatts converts to approximately 2,682,044,179.2 Horsepower

Common Use Cases

Relating national or global electricity generation figures expressed in terawatts to mechanical units
Comparing the aggregated capacity of large power plants with familiar engine power ratings
Contextualizing astrophysical power outputs such as stellar luminosities in conventional power units
Supporting automotive and mechanical engineering assessments involving very large power scales

Tips & Best Practices

Keep in mind that horsepower definitions vary, so clarify which variant applies to your needs
Use this converter for interpreting extremely large power values rather than everyday machinery powers
Cross-check results if precise engineering calculations are required due to variant horsepower values
Use the tool as a quick reference to bridge large-scale and conventional power units

Limitations

Horsepower units differ by type and exact conversion values may vary accordingly
Terawatt values represent extremely large power levels, which can yield huge horsepower results not practical for everyday use
Exact precision depends on assumptions about the watt-to-horsepower relationship and rounding
This converter provides general conversions but not variant-specific horsepower calculations
