`FxR = 100^[((m_2 - m_1)/5)] `

1

The **Flux Ratio from Magnitudes** calculator computes the ratio of the intensity of light coming from two celestial objects based on their magnitudes (m_{1} and m_{2}).

**INSTRUCTIONS:** Enter the following:

- (
**m**) Intensity of light magnitude associated with object 1._{1} - (
**m**) Intensity of light magnitude associated with object 2._{2}

**Flux Ratio (FxR):** The calculator returns the flux ratio.

The **Flux Ratio from Magnitudes** is the ratio of the intensity of light coming from two celestial objects based on their magnitudes. Two different objects with magnitudes m_{1} and m_{2} have a corresponding flux ratio given by this formula:

`FxR = 100^((m_2−m_1) / 5)`

where:

- FxR = Flux Ratio
- m
_{2}= magnitude of first object - m
_{1}= magnitude of second object

The flux ratio, f_{2}/f_{1} is the ratio of the intensity of light coming from object 1 compared to the intensity coming from object 2.
