# Cosmological Matter Density Parameter Calculator

The term cosmology is the astronomical branch deals with the origin and development of the universe. According to Friedmann equations, the matter density parameter is defined as the ratio of the observed density to the critical density. Enter the values of density and Hubble value in the cosmological matter density parameter calculator to find the density value.

The matter density parameter can be calculated using this simple online cosmological matter density parameter calculator with the values of gravitational constant, density and Hubble value. The calculations are done using the Friedmann equations which are the set of equations in physical cosmology that govern the expansion of space in homogeneous and isotropic models of the universe within the context of general relativity.
