API, OpenAPI and WebMCP documentation

Explanation

Hours converts into kilowatt-hours with a fixed 3W load. kWh = (hours x 3) / 1000. The direct answer, calculator, common values, and mirror page all stay aligned on that same runtime assumption for standby electronics and light network gear.

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 Hours to Kilowatt-hours at 3W load calculated?

kWh = (hours x 3) / 1000. Continuous load is fixed at 3W, so every result uses the same runtime relationship.

What does the fixed 3W load mean?

The calculator assumes a constant 3W power draw, which makes the runtime estimate suitable for standby electronics and light network gear.

Can I use this Hours to Kilowatt-hours at 3W load page for runtime planning?

Yes, as a first-pass estimate. The mirror Kilowatt-hours to Hours at 3W load page handles the inverse direction, but real systems can still vary because of efficiency losses and battery aging.
