Convert Milligal to Kilometres per hour per second

Convert Milligal (mGal) to Kilometres per hour per second (km/h/s) instantly and accurately.

Conversion Formula

km/h/s = mGal × 3.600000000e-5

About Milligal

The milligal (mGal) equals 10⁻⁵ m/s², the standard unit for geophysical gravity surveys. Bouguer gravity anomalies - reported in mGal after latitude and terrain corrections - reveal subsurface density contrasts: salt domes give +5 to +50 mGal, oceanic spreading ridges -200 to -300 mGal. Standard gravity is ≈ 980 765 mGal at sea level. The International Gravity Reference Frame 2016 is tied to absolute stations accurate to 0.01 mGal. 1 mGal = 10⁻⁵ m/s² ≈ 1.02 × 10⁻⁶ g₀.

About Kilometres per hour per second

The kilometre per hour per second (km/h/s) equals 1/3.6 m/s² ≈ 0.2778 m/s², the most intuitive acceleration unit for vehicle performance in countries using km/h. A 0-100 km/h time of 6.3 s (VW Golf GTI) gives a mean acceleration of 15.9 km/h/s ≈ 4.4 m/s²; a 2.6 s EV sprint corresponds to 38.5 km/h/s ≈ 10.7 m/s². Railway standards (EU TSI, JIS) use km/h/s: high-speed trains launch at 2.5-4 km/h/s; emergency braking must reach at least 9.0 km/h/s. 1 km/h/s = 1/3.6 m/s² ≈ 2.83 × 10⁻² g₀.
