Weight on the Sun Formula

The following two example problems outline the steps and information needed to calculate the Weight on the Sun.

SW = EW × (gₛᵤₙ / gₑₐᵣₜₕ) ≈ EW × 27.9

Variables:

  • SW is the weight on the Sun (same unit as EW, e.g., lb)
  • EW is the weight on Earth (same unit as SW, e.g., lb)
  • gₛᵤₙ is the Sun’s surface gravitational acceleration
  • gₑₐᵣₜₕ is Earth’s surface gravitational acceleration

How to Calculate Weight on the Sun?

The following steps outline how to calculate the Weight on the Sun.


  1. First, determine the weight on Earth (lb). 
  2. Next, gather the formula from above: SW = EW × (gₛᵤₙ / gₑₐᵣₜₕ) ≈ EW × 27.9.
  3. Finally, calculate the Weight on the Sun.
  4. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

Weight on Earth (lb) = 250

SW = EW × 27.9 = 250 × 27.9 ≈ 6,975 lb
