## How the Matter Density Parameter Is Found
The density parameter Omega_m tells us the fraction of the universe's critical density that is in the form of matter.
### Formula
**Omega_m = rho_m / rho_crit**
- *rho_m* is the average matter density
- *rho_crit* is the critical density
If Omega_total = 1 the universe is geometrically flat. Current measurements give Omega_m about 0.31.

हल किया गया उदाहरण
With rho_m = 2.65e-27 kg/m³ and rho_crit = 9.47e-27 kg/m³.
- Omega_m = rho_m / rho_crit
- Omega_m = 2.65e-27 / 9.47e-27
- Omega_m ≈ 0.2799
