How it works

All paths go through Celsius: F = C x 9/5 + 32; K = C + 273.15.

Tips

  • 0 C = 32 F = 273.15 K is a handy anchor.
  • Body temperature: 37 C ≈ 98.6 F.

Limitations

Rounding follows standard conventions (±0.01).

Frequently asked questions

How do I convert F to C?

(F - 32) x 5/9. So 98.6 F = 37 C. The tool shows this formula each time.

Why is Kelvin different?

Kelvin is an absolute scale — 0 K is absolute zero. K = C + 273.15.

Can I convert all three at once?

Yes — enter any unit and see the equivalent in the other two simultaneously.
