Overview
Acceleration measures how quickly velocity changes per unit time. Common uses:
- Physics & engineering (m/s², ft/s²).
- Gravimetry (Gal, standard gravity g).
- Aerospace & vehicle testing (mph/s, knot/s).
Formula & Methodology
All units convert ↔ through the base unit m/s². Conversion steps:
- Multiply your input by (factor → m/s²).
- Divide that m/s² by (factor → m/s² for the target unit).
Below is the conversion table (Unit → m/s²):
| Unit | Symbol | Factor (→ m/s²) | Notes / Definition |
|---|---|---|---|
| Metre per second squared | m/s² | 1 | SI base |
| Foot per second squared | ft/s² | 0.3048 | 1 ft = 0.3048 m → (ft/s² → m/s²) |
| Galileo | Gal | 0.01 | 1 Gal = 0.01 m/s² (gravimetry) |
| Standard gravity | g | 9.80665 | g₀ = 9.80665 m/s² |
| Foot per minute per second | ft/min/s | 0.3048 ÷ 60 ≈ 0.00508 | 1 ft/min ↑ per second |
| Foot per hour per second | ft/hr/s | 0.3048 ÷ 3600 ≈ 8.4667×10⁻⁵ | 1 ft/hr ↑ per second |
| Inch per second squared | in/s² | 0.0254 | 1 in = 0.0254 m → (in/s² → m/s²) |
| Inch per minute per second | in/min/s | 0.0254 ÷ 60 ≈ 0.00042333 | 1 in/min ↑ per second |
| Knot per second | kn/s | 0.514444 | 1 kn = 0.514444 m/s → per s = 0.514444 m/s² |
| Mile per hour per second | mph/s | 0.44704 | 1 mph = 0.44704 m/s → per s = 0.44704 m/s² |
| Mile per minute per second | mi/min/s | 26.8224 | 1 mi/min = 26.8224 m/s → per s = 26.8224 m/s² |
| Mile per second squared | mi/s² | 1609.344 | 1 mi = 1609.344 m → per s² |
| Foot per minute squared | ft/min² | 0.3048 ÷ 3600 ≈ 8.4667×10⁻⁵ | 1 ft/min² → m/s² |
| Inch per second squared (alternative) | in/s² | 0.0254 | Same as above—duplicate symbol |

Convert 10 ft/s² to m/s²:
10 × 0.3048 = 3.048 m/s² -
Convert 500 Gal to g:
500 × 0.01 = 5 m/s² → 5 ÷ 9.80665 ≈ 0.510 g -
Convert 2 mph/s to ft/s² (Advanced Mode):
2 × 0.44704 = 0.89408 m/s² → 0.89408 ÷ 0.3048 ≈ 2.931 ft/s² -
Convert 100 in/min/s to Gal (Advanced Mode):
100 × 0.00042333 = 0.042333 m/s² → 0.042333 ÷ 0.01 = 4.233 Gal -
Convert 1 g to mph/s (Advanced Mode):
1 × 9.80665 = 9.80665 m/s² → 9.80665 ÷ 0.44704 ≈ 21.94 mph/s
Frequently Asked Questions
Why use m/s² as the base unit?
Because m/s² is the SI unit for acceleration. Converting everything through m/s² ensures consistency and minimizes rounding errors.
What is the difference between ft/s² and ft/min/s?
ft/s² means speed increases by 1 foot every second, each second. ft/min/s means speed increases by 1 foot per minute, each second (much smaller).
How does “Gal” relate to “g” (standard gravity)?
1 Gal = 0.01 m/s². Standard gravity (g₀) is 9.80665 m/s², so 1 g₀ = 980.665 Gal.
When would I use mph/s vs. knot/s?
mph/s is common in vehicle testing (speed increase in mph per second). knot/s is used in aviation or marine (knots per second change).
