How this multi converter works
Each category normalizes your input into a base unit and recalculates it in the target unit. Non-linear categories such as temperature and fuel economy use dedicated formulas.
Usage notes
- Normalize to a base unit
- Recalculate into the selected target unit
- Update results instantly as you type
- Combine day/hour/minute/second in the time tab
Frequently asked questions

Yes. Each tab stores its own state, so switching tabs does not wipe your previous input.
Are temperature and fuel conversions linear? expand_more
No. They use dedicated formulas instead of simple multiplication factors.
Does this work the same on mobile? expand_more
Yes. The same conversion engine powers every breakpoint with a responsive layout.
