How to Convert .15Mo/pc^3 to g/cm^3?

Click For Summary
SUMMARY

The discussion focuses on converting a density value of 0.15 Mo/pc³ into g/cm³. Participants confirm that to perform the conversion, one must multiply 0.15 by the solar mass (1.9e33 g) and then divide by the cube of the parsec (3e18 cm). The correct formula for the conversion is 0.15 * (1.9e33 g / (3e18 cm)³), ensuring that the units are consistent throughout the calculation.

PREREQUISITES
  • Understanding of unit conversion in physics
  • Familiarity with solar mass as a unit of mass
  • Knowledge of parsec as a unit of distance
  • Basic algebra for manipulating equations
NEXT STEPS
  • Research the concept of density and its units in astrophysics
  • Learn about unit conversion techniques in scientific calculations
  • Explore the significance of solar mass in astrophysical contexts
  • Study the relationship between different astronomical units, such as parsecs and centimeters
USEFUL FOR

Astronomy students, physicists, and anyone involved in astrophysical calculations who needs to understand unit conversions and density measurements.

Homework Statement


I am giving .15Mo/pc^3 how can i convert that into g/cm^3
mo is solar mass and its in grams and pc is distance so its in cm so wht would i do to convert it?


Homework Equations





The Attempt at a Solution


would i just mutiply .15 by the solarmass(1.9e33g) than divide by pc^3 which is (3e18 cm)
so would i do .15((1.9e33/(3e18^3) ?

i assume you mean .15((1.9e33/(3e18)^3) ? :wink:

yes, that's correct …

in dimensions questions like this, you use the conversion factor to the same power as the unit appears it the formula :smile:

(if it makes you happier, you can check it by writing 1 Mo/pc3 = 1 (Mo/g) (cm/pc)3 g/cm3 :wink:)
 
will do... k thxs for the reply
