The **Relative Temperature from Relative Size and Luminosity** calculator returns the relative temperature based on the relative size and relative luminosity.

**INSTRUCTIONS:** Enter the following:

- (
**L**) This is the relative luminosity. - (
**R**) This is the relative size (radius).

**Relative Stellar Temperature:** The calculator returns the relative temperature.

A stars temperature can be determined if you know the relative size and luminosity compared to the Sun. Suppose a star is twice the size of the sun with 10 times the luminosity? Use: R=2 and L=10 to find:

T=(10/2^2)^(0.25)
