About these units
Earth's Velocity (v⊕)
Earth's orbital velocity around the Sun averages about 29.78 km/s, or roughly 107,000 km/h. This enormous speed is imperceptible to us because everything on Earth—including its atmosphere—moves with the planet. Earth's velocity varies slightly over the year due to its elliptical orbit, being fastest at perihelion (closest to the Sun) and slowest at aphelion (farthest distance). This velocity influences astronomical observations, Doppler shifts in starlight, and the calibration of spacecraft navigation. Earth's motion through the Solar System is a reminder that even when we feel stationary, we are traveling at extraordinary speeds through space.
Mach (20°C, 1 atm) (Ma (20°C))
At 20°C and 1 atmosphere, the speed of sound in air is about 343 m/s, making Mach 1 = 343 m/s under those conditions. Mach numbers classify aerodynamic regimes: Mach 0.3–0.8 (Subsonic), Mach 0.8–1.2 (Transonic), Mach 1–5 (Supersonic), Mach 5+ (Hypersonic). Temperature influences Mach speed significantly; colder air slows sound, while warmer air increases its speed. Aircraft design, jet engines, wind tunnels, aerospace testing, and atmospheric re-entry physics all rely heavily on Mach numbers referenced to standard conditions.
