CosmoCalc is a simple cosmological distance calculator. With a simple and intuitive interface you can quickly set a reference cosmology and redshift, and CosmoCalc will calculate a full suite of astronomical distances and scales.
CosmoCalc is a useful and educational reference tool for astronomers, astronomy students, and anybody interested in calculating the distance to astronomical sources.
CosmoCalc allows you to:
* Select cosmological parameters H_0, Ω_m, and Ω_Λ with simple touch-screen controls
* Easily choose from common reference cosmologies, including Planck 2013, WMAP9, Concordance, and Einstein-deSitter
* Quickly determine the luminosity distance, angular diameter distance, lookback time, age of the Universe, comoving volume, and critical density
* Easily switch between flat and non-flat cosmologies by clicking on the chain
