Acceleration Converter

Multiply g by 9.80665 to get m/s². One standard gravity (1g) equals exactly 9.80665 m/s². A fighter jet pilot experiences up to 9g (88.3 m/s²) during sharp turns, while astronauts feel about 3g during launch.

A moderate car crash at 30 mph produces about 30g of deceleration. A head-on collision at 60 mph can exceed 100g. For comparison, a roller coaster peaks at about 3-6g, a sneeze produces around 3g and normal braking in a car is about 0.3-0.8g.

The Gal (named after Galileo) equals 0.01 m/s² or 1 cm/s². It is primarily used in geophysics and seismology to measure gravitational acceleration variations. Earth's gravity is about 980 Gal. Seismic instruments often report in milligal (0.001 Gal) for precision.

Divide km/h/s by 3.6 to get m/s². A car that accelerates 0-100 km/h in 5 seconds has an average acceleration of 20 km/h/s or about 5.56 m/s² (0.57g). A Tesla Model S Plaid hits about 28.8 km/h/s (8 m/s² or 0.82g).

Mars has 3.72 m/s² (0.38g), Jupiter has 24.79 m/s² (2.53g) and the Moon has 1.62 m/s² (0.17g). This means a person weighing 70 kg on Earth would feel like 26.6 kg on Mars and 177 kg on Jupiter.
