Question

the SI unit of universal gravitational constant​

Answer 1

The dimensions assigned to the gravitational constant are force times length squared divided by mass squared; this is equivalent to length cubed, divided by mass and by time squared: In SI base units, this amounts to meters cubed per kilogram per second squared: In cgs, G can be written as G ≈ 6.674×10−8 cm3⋅g−1⋅s−2.
