9.80665 m/s²
How these units are defined
Standard gravity is defined as exactly 9.80665 m/s². Density and flow factors follow from the length, mass and volume definitions (for example 1 US gallon per minute = 3.785411784 L/min).
Acceleration
| Unit | Equals |
|---|---|
| 1 G-force | 9.80665 m/s² |
| 1 ft/s² | 0.3048 m/s² |
Density
| Unit | Equals |
|---|---|
| 1 g/cm³ | 1,000 kg/m³ |
| 1 lb/ft³ | 16.01846337 kg/m³ |
Flow Rate
| Unit | Equals |
|---|---|
| 1 GPM | 3.785411784 L/min |
| 1 CFM | 28.31684659 L/min |
Worked examples
- 1 G-force = 9.80665 m/s²
- 10 G-force = 98.0665 m/s²
- 100 G-force = 980.665 m/s²
Common mistakes
- Actual gravity varies from about 9.78 m/s² at the equator to 9.83 m/s² at the poles; "g" here is the defined standard value.
- GPM here means US gallons per minute; UK pump literature may use imperial gallons (4.546 L).
