About this calculator
Surface gravity table: g varies wildly across the solar system. Mercury & Mars share ~3.7 m/s² (about ⅜ Earth). Moon: 1.62 (just 1/6). Jupiter: 24.79 (2.5×!). Saturn comparable to Earth despite much greater mass — because of larger radius (g = GM/r²). Pluto: 0.62, near-weightless.
Frequently asked
g = GM/r². Combination of mass and radius. Big-mass-big-radius (Saturn) ≈ small-mass-small-radius (Earth).

Wind Speed mph ↔ Knots
1 knot = 1.15078 mph = 1.852 km/h. Bidirectional, also m/s.
Temperature Rankine ↔ Fahrenheit
R = F + 459.67. Rankine is absolute (0 = absolute zero); Fahrenheit + 460.
Pressure psi ↔ bar
1 bar = 14.5038 psi = 100 kPa = 0.987 atm.
Pressure bar ↔ atm
1 atm = 1.01325 bar = 14.696 psi.
Time Seconds ↔ Minutes / Hours
Convert seconds to days/hours/minutes/seconds; auto-format hh:mm:ss.
