Definition of Milligal
Milligal: The Geophysicist's Precision Unit
The milligal (mGal) is one-thousandth of a Galileo (Gal), equal to 0.00001 m/s² or 10 µm/s². It is the standard unit in gravimetry — the science of measuring gravitational field variations.
Conversions to Other Units of Measurement:
- Meter per Second Squared (m/s²): 1 mGal = 0.00001 m/s² (10⁻⁵ m/s²).
- Galileo (Gal): 1 mGal = 0.001 Gal exactly.
- Standard Gravity (g): 1 mGal ≈ 1.0197 × 10⁻⁶ g. Standard gravity is approximately 980,665 mGal.
- Microgal (µGal): 1 mGal = 1000 µGal.
Modern gravimeters can measure variations of just a few microgal (µGal), enabling detection of underground geological structures, tidal effects, and even the gravitational attraction of nearby buildings.
- Definition
- Geophysical unit; 1/1000 of a Galileo, used for precision gravity measurements.
- Exact factor
- 1 mGal = 10⁻⁵ m/s² = 0.001 Gal
- Common equivalents
- 1 mGal = 0.00001 m/s²
- 1 mGal = 0.001 Gal
- 1 mGal ≈ 1.02 × 10⁻⁶ g
- Context
- Oil exploration gravity surveys typically look for anomalies of 1-10 mGal
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 Milligal
The milligal reveals Earth's hidden geology. Gravity surveys conducted from aircraft (airborne gravimetry) can detect density variations underground by measuring gravity changes of just 1-2 mGal. This technique has led to the discovery of numerous oil and mineral deposits.
Even the Moon creates measurable tidal effects on Earth of about ±0.1 mGal, and the gravitational pull of a large mountain can create anomalies of several hundred mGal compared to surrounding flatlands.
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.
Frequently Asked Questions
How many galileos are in one milligal?
One milligal equals 0.001 galileos. To convert, multiply the milligal value by 0.001. For the reverse, divide the galileo value by 0.001 (or multiply by 1000).
What is 100 milligals in galileos?
100 milligals = 0.1 galileos. This is one of the most commonly searched conversions for this pair.
Is the milligal-to-galileo conversion exact?
Yes. The factor 0.001 is exact by international definition, not an approximation. Any imprecision comes only from the original measurement, not the conversion.
