How fast in parsecs is the universe expanding?
Based on the average of measurements and analysis, it is a scientific surmise that our universe is expandingat the rate of 72 km/sec/megaparsec. 72 km in parsec unit is nearly 3.3E-13 parsec
The rate is less than 1 in 30000000000000000000 /sec in parsec for radial distance. Mega parsec is 1000000 parsec. i parsec is nearly 200000 AU and 1 AU is nearly 1.5E+08 km.
