1.019716213 Standard Gravity
Acceleration measures the rate at which an object's velocity changes over time (Δv / Δt). In the International System of Units (SI), linear acceleration is expressed in meters per square second (m/s²). Customary systems use feet per square second (ft/s²), while automotive contexts use speed-over-time measures such as mph/s or 0-60 mph times.
Standard gravity (symbol: g) is the nominal acceleration of an object in a vacuum near the surface of the Earth, officially standardized as 9.80665 m/s² (32.174 ft/s²). Human beings experience 1 g under normal conditions, while trained fighter pilots wearing anti-G suits can tolerate up to 9 g before experiencing blackout.
In geology, geophysics, and oil/mineral prospecting, variations in the Earth's local gravitational pull are measured using the Gal (1 cm/s² = 0.01 m/s²) and milligal (mGal = 10⁻⁵ m/s²). Gravimeters detect micro-anomalies caused by underground salt domes, mineral deposits, and tectonic fault lines.
1 g (standard Earth gravity acceleration) is defined as exactly 9.80665 m/s² (approx 32.174 ft/s²).
To convert meters per square second to feet per square second, multiply by 3.28084. For example, 10 m/s² × 3.28084 = 32.8084 ft/s².
A Gal (named after Galileo Galilei) is a CGS unit of acceleration equal to 1 centimeter per second squared (0.01 m/s²), widely used in gravimetry and earthquake seismology.
A sports car accelerating from 0 to 60 mph in 3.0 seconds experiences an average forward acceleration of approximately 0.91 g (8.94 m/s²). Accelerating in 2.0 seconds corresponds to 1.37 g.
