astronomical magnitude flux ratio calculator online

Use astronomical magnitude flux ratio online for magnitude1, magnitude2. Idealized astronomical model with displayed units. Seeing, extinction, instrument losses or cosmological effects apply only when explicitly included.

How to use it

Enter magnitude1. Set magnitude2. Select Calculate and check the labeled output. Copy or download the JSON result.

Options and example settings

OptionChoices / valueExample default
magnitude1Main input. Signed finite values. 2
magnitude2Option. Signed finite values. 5

Calculation method

flux1_over_flux2 = 10^((magnitude2-magnitude1)/2.5) (^ means exponentiation; trig functions ending in d use degrees).

Worked examples

Apply astronomical magnitude flux ratio to the case below, keeping the displayed units and assumptions. Idealized astronomical model with displayed units. Seeing, extinction, instrument losses or cosmological effects apply only when explicitly included.

Choose the right tool

Use telescope calculators for focal lengths and angular scale, magnitude tools for logarithmic brightness relationships, and orbit tools for the specified gravitational model. Check whether a distance is in parsecs, light-years or astronomical units.

Limitations and common mistakes

  • Idealized astronomical model with displayed units. Seeing, extinction, instrument losses or cosmological effects apply only when explicitly included.
  • Use the displayed unit in every field. Ratios and percentages are different inputs; percent fields use values such as 25 rather than 0.25.
