Unit Conversion: G 6.67x10^-11 m^3*s^-2*kg^-1 to cm^3*s^2*g^-1

Click For Summary
SUMMARY

The gravitational constant G, valued at 6.67 x 10^-11 m^3*s^-2*kg^-1, can be converted to cm^3*s^2*g^-1 by applying unit conversion principles. The conversion involves recognizing that 1 kg equals 1000 g and 1 m equals 100 cm. The correct conversion results in G being expressed as 6.67 x 10^-5 cm^3*s^2*g^-1. A common misconception addressed in the discussion is the misunderstanding of dimensional consistency during unit conversion, specifically regarding the exponent of time.

Homework Statement


"The gravitational constant G is 6.67*10^-11 m^3*s^-2*kg^-1. What is G in units of cm^3*s^2*g^-1


Homework Equations


1kg = 1000g
1m = 100cm


The Attempt at a Solution



I don't understand how the dimension can change from [L^3,T^-2,M^-1] to [L^3,T^2,M^-1], shouldn't the dimension stay consistent even if the units change?

Yes, it's a typo, they are missing a minus sign on that "s" exponent.
