Acceleration Converter

Convert acceleration between m/s², ft/s², g-force, and other acceleration units.

Convert Units

Convert acceleration measurements between different units including meters per second squared, feet per second squared, g-force, and more.

What is Acceleration Converter?

Acceleration is the rate of change of velocity over time. It is a vector quantity, meaning it has both magnitude and direction. Acceleration is fundamental in physics, engineering, automotive design, and aerospace applications.

Understanding the Units

Meter per Second Squared (m/s²)

The SI unit of acceleration. Represents the change in velocity in meters per second, per second.

Common Uses: Physics, engineering, scientific calculations

Reference: Standard gravity (g) ≈ 9.80665 m/s²

G-Force (g)

Acceleration relative to standard Earth gravity. 1g equals the acceleration due to gravity at Earth's surface.

Common Uses: Aviation, aerospace, automotive performance, amusement rides

Reference: 1g = 9.80665 m/s²

Foot per Second Squared (ft/s²)

Imperial unit of acceleration commonly used in the United States.

Common Uses: Engineering in the US, construction

Conversion: 1 ft/s² = 0.3048 m/s²

Common Conversions

  • Standard gravity: 1g = 9.80665 m/s² = 32.174 ft/s²
  • Sports car acceleration: 0-60 mph in 3 seconds ≈ 0.91g
  • Fighter jet: Can experience 9g during maneuvers
  • Space shuttle launch: ~3g maximum acceleration

Conversion Formulas

  • Basic acceleration: a = Δv / Δt (change in velocity / change in time)
  • m/s² to g: g = m/s² ÷ 9.80665
  • g to m/s²: m/s² = g × 9.80665
  • ft/s² to m/s²: m/s² = ft/s² × 0.3048

Practical Examples

Free fall on Earth: 9.8 m/s² or 1g downward

High-performance car: 0-100 km/h in 3 seconds ≈ 9.3 m/s²

Roller coaster: Can reach 4-6g during loops

Astronauts during launch: Experience 3-4g

When to Use Each Unit

m/s²: Physics, engineering, and scientific calculations (SI standard)
g-force (g): Aviation, aerospace, motorsport, and roller coaster ratings
ft/s²: Engineering and construction applications in the United States
