Henry (H) and Watt (W) measure different electrical quantities. See how they relate and use context values for a physically meaningful result.
Context values
Some unit families need one extra value for a physically accurate result.
The watt (W) is the SI unit of power, equal to one joule of energy transferred per second.
No fixed factor — different physical quantities
Henry measures inductance and Watt measures electrical power. These are different physical quantities, so there is no fixed multiplication factor between them. Use Ohm’s law and energy over time: V = I × R, P = V × I, E = P × time.

Compatibility notice
Henry (H) measures inductance. Watt (W) measures electrical power. Because these are different physical dimensions, there is no single fixed factor that converts one directly into the other — a numeric answer would be fabricated and misleading.
Related through Ohm's Law (V = I × R) and the power law (P = V × I), with energy linked to power over time (E = P × t). Enter voltage, current, resistance, and/or hours in the context fields above the result to get a physically accurate value based on the relationship between henry and watt.
Conversion table
A direct numeric table is not shown here because henrys and watts are not directly proportional. Instead, use the calculator above with context values, or convert within a single dimension using the related conversions below.

How henrys and watts relate
Henry and Watt belong to different electrical dimensions (inductance vs. electrical power), so this page does not fabricate a fixed conversion formula. Related through Ohm's Law (V = I × R) and the power law (P = V × I), with energy linked to power over time (E = P × t). Supply the missing context (voltage, current, resistance, or time) in the calculator to compute a real-world equivalent.
Frequently asked questions
Can I convert henrys directly to watts?
