API, OpenAPI and WebMCP documentation

Explanation

Watt-hours converts into hours with a fixed 25W load. hours = Wh / 25. The direct answer, calculator, common values, and mirror page all stay aligned on that same runtime assumption for mobile workstation standby usage.

Method & Profile Basis

Profile basis: output depends on the selected page-specific profile and keeps the same assumptions in both directions.
Profile reference: load profile.
Consistency rule: calculator output and table values use the same profile assumptions in both directions.

Questions & answers

Frequently Asked Questions

How is Watt-hours to Hours at 25W load calculated?

hours = Wh / 25. Continuous load is fixed at 25W, so every result uses the same runtime relationship.

What does the fixed 25W load mean?

The calculator assumes a constant 25W power draw, which makes the runtime estimate suitable for mobile workstation standby usage.

Can I use this Watt-hours to Hours at 25W load page for runtime planning?

Yes, as a first-pass estimate. The mirror Hours to Watt-hours at 25W load page handles the inverse direction, but real systems can still vary because of efficiency losses and battery aging.
