SUMMARY

The discussion centers on ensuring consistency in unit systems, specifically when dealing with density and rotation. The user emphasizes the importance of using a consistent unit system, such as MKS (Meter-Kilogram-Second) or CGS (Centimeter-Gram-Second), to avoid confusion. For density, the appropriate unit is kilograms per cubic meter (kg/m³) when using MKS. For rotation, radians per second (rad/s) is the standard unit in this context. The conversation highlights the necessity of adhering to a single unit system to maintain clarity in calculations.

PREREQUISITES
  • Understanding of unit systems, specifically MKS and CGS.
  • Familiarity with basic physics concepts, including force, stress, and density.
  • Knowledge of unit conversions and their implications in calculations.
  • Basic grasp of rotational dynamics and angular measurements.
NEXT STEPS
  • Research the properties and applications of MKS and CGS unit systems.
  • Learn about density calculations and conversions in various unit systems.
  • Explore the concept of angular velocity and its measurement in radians per second.
  • Investigate common pitfalls in unit conversions and how to avoid them.
USEFUL FOR

Engineers, physicists, and students in scientific fields who require a clear understanding of unit consistency in calculations involving density and rotation.

Please can anyone help me?I'm confused here.

If I'm following unit of force as Newton, and length as mm; and stress as MPa,then for a consistent system of units (see link below);

http://www.dynasupport.com/howtos/general/consistent-units/

what should be the unit for:
1)density
2) rotation

for me I would convert everything to MKS and then work it out rather than mix and match various units of measure unless there is a clear reason to do otherwise. Similarly for choosing CGS...
