Discussion Overview

The discussion revolves around the correct representation of Einstein's equation E=mc², specifically focusing on the units of measurement for mass and energy. Participants are checking the accuracy of an explanation intended for an article, with an emphasis on the proper use of SI units.

Discussion Character

  • Technical explanation

Main Points Raised

  • One participant presents an initial explanation of E=mc², using grams for mass and Joules for energy.
  • Another participant corrects the mass unit to kilograms, indicating that the standard SI unit should be used.
  • A later reply confirms the correction regarding the use of kilograms.

Areas of Agreement / Disagreement

Participants generally agree on the need to use kilograms for mass in the equation, but the initial explanation contained inaccuracies that were addressed through corrections.

Contextual Notes

The discussion highlights the importance of using correct units in scientific equations, but does not delve into deeper implications or applications of the equation itself.

I am doing an article that includes a brief explanation of Einstein's basic equation, and want to check my work. As I understand it, the equation is e(energy in Joules)=m(in grams)×speed of light in meters/second squared(9×10 to the 16th). Is this reasonably correct? Thanks.

Kilograms
 
Almost. In SI units m is in kilograms.

Edit: V50 for the win!
 
Kilograms it is. Thanks to both for the double-check!
