Astronomy
Distance Modulus Calculator
Compute distance to a celestial object in parsecs from its apparent and absolute magnitudes using the distance modulus formula d = 10^((m − M + 5)/5). The standard "standard candle" technique for measuring distances across the Milky Way and to nearby galaxies.

Astronomy
Apparent Magnitude Calculator
Convert a star's absolute magnitude and distance in parsecs into its apparent magnitude — how bright it looks from Earth. Essential for astronomy students comparing stellar brightness across different distances.
