Astronomy
Stellar Distance Calculator
Convert a star's measured parallax angle into its distance in parsecs and light-years using the standard parallax formula. Useful for astronomy students and observers working with Hipparcos or Gaia catalog data.

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 โ M + 5)/5). The standard "standard candle" technique for measuring distances across the Milky Way and to nearby galaxies.
