Definition of Standard Gravity
Standard Gravity: Earth's Reference Acceleration
Standard gravity (symbol: g or gₙ) is the nominal gravitational acceleration of an object at Earth's surface at sea level. It is defined as exactly 9.80665 m/s². This value was established by the 3rd General Conference on Weights and Measures (CGPM) in 1901 and serves as a reference for comparing accelerations.
Conversions to Other Units of Measurement:
- Meter per Second Squared (m/s²): 1 g equals exactly 9.80665 m/s². This is the internationally agreed standard value used in science and engineering.
- Foot per Second Squared (ft/s²): 1 g is approximately 32.174 ft/s². This value is commonly used in US aerospace and engineering applications.
- Galileo (Gal): 1 g equals 980.665 Gal. Since 1 Gal = 1 cm/s², this conversion is straightforward and used in geophysical measurements.
- Kilometer per Hour per Second (km/h/s): 1 g equals approximately 35.30 km/h/s. A sports car accelerating at 1 g would gain about 35 km/h every second.
- Mile per Hour per Second (mph/s): 1 g is approximately 21.94 mph/s. Fighter pilots can experience accelerations of 9 g or more during combat maneuvers.
Standard gravity is essential in defining units like the kilogram-force and in expressing accelerations experienced by humans in vehicles, aircraft, and spacecraft.

Definition of Galileo
Galileo (Gal): The CGS Unit of Acceleration
The Galileo (symbol: Gal) is a unit of acceleration named after Italian scientist Galileo Galilei. It is defined as 1 centimeter per second squared (1 cm/s² = 0.01 m/s²). The Gal is primarily used in geodesy and geophysics for measuring very small accelerations, such as variations in Earth's gravitational field.
Conversions to Other Units of Measurement:
- Meter per Second Squared (m/s²): 1 Gal equals exactly 0.01 m/s². This straightforward conversion makes it easy to work between CGS and SI systems.
- Standard Gravity (g): 1 Gal is approximately 0.00102 g, or about 1 milligal (mGal) = 1.02 × 10⁻⁶ g. The milligal (0.001 Gal) is commonly used in gravimetry.
- Foot per Second Squared (ft/s²): 1 Gal equals approximately 0.03281 ft/s².
- Inch per Second Squared (in/s²): 1 Gal equals approximately 0.3937 in/s².
- Kilometer per Hour per Second (km/h/s): 1 Gal equals 0.036 km/h/s.
Gravimeters used in mineral exploration and geophysical surveys typically measure in milligals or microgals to detect subtle density variations underground.

About the Standard Gravity
Standard gravity affects everything on Earth. When you jump, you accelerate downward at 1 g. Roller coasters can subject riders to 3-4 g during loops and drops. Fighter pilots train to withstand up to 9 g using special suits and techniques.
Interestingly, Earth's actual gravitational acceleration varies slightly by location—from about 9.78 m/s² at the equator to 9.83 m/s² at the poles—due to Earth's rotation and shape. The standard gravity value (9.80665 m/s²) is an internationally agreed reference.
About the Galileo
Named after Galileo Galilei, who first accurately described gravitational acceleration, the Gal is essential in geophysics. Gravimeters can detect changes as small as 1 microgal (10⁻⁸ m/s²)—enough to measure the gravitational pull of a nearby building!
Oil and mineral exploration companies use gravity surveys measuring in milligals to locate underground deposits. Dense ore bodies create measurable gravity anomalies that help geologists find resources.
