Formula used

Weight (force): W = m × g

W is weight, m is mass, and g is gravitational acceleration.

Work / gravitational energy: E = W × h = m × g × h

Use height h to estimate the energy in erg.

Unit links: 1 N = 105 dyn, and 1 J = 107 erg.

How to use this calculator
  1. Enter a mass and pick its unit.
  2. Select a gravity option: standard, custom, or latitude-based.
  3. Optional: add height/distance to compute energy in erg.
  4. Press Calculate to show results above the form.
  5. Use CSV or PDF buttons to export the results.
