planet surface gravity in earth units calculator online

Use planet surface gravity in earth units online for mass earth, radius earth. Idealized astronomical model with displayed units. Seeing, extinction, instrument losses or cosmological effects apply only when explicitly included.

How to use it

Enter mass earth. Set radius earth. Select Calculate and check the labeled output. Copy or download the JSON result.

Options and example settings

OptionChoices / valueExample default
mass earthMain input. Positive values. 1
radius earthOption. Positive values. 1

Calculation method

relative_gravity = mass_earth/radius_earth^2 (^ means exponentiation; trig functions ending in d use degrees).

Worked examples

Apply planet surface gravity in earth units to the case below, keeping the displayed units and assumptions. Idealized astronomical model with displayed units. Seeing, extinction, instrument losses or cosmological effects apply only when explicitly included.

Choose the right tool

Use telescope calculators for focal lengths and angular scale, magnitude tools for logarithmic brightness relationships, and orbit tools for the specified gravitational model. Check whether a distance is in parsecs, light-years or astronomical units.

Limitations and common mistakes

  • Idealized astronomical model with displayed units. Seeing, extinction, instrument losses or cosmological effects apply only when explicitly included.
  • Use the displayed unit in every field. Ratios and percentages are different inputs; percent fields use values such as 25 rather than 0.25.
