About

Acceleration Calculator

Calculate acceleration, speed, or time with this physics utility. Supports numerous units for vehicles and objects, providing results in m/s² and gravity units. Can also calculate deceleration and braking distances.

Highlights
  • Calculate acceleration, initial/final speed, or time
  • Supports metric and imperial units
  • Results in m/s² and gravity units (g)
  • Calculates deceleration and braking distance
  • Input three of four parameters to find the missing one

Effortlessly determine acceleration, initial and final speed, or time required to reach a specified speed using our acceleration calculator. The tool supports various metrics, including meters per second, miles per hour, miles per second, kilometers per hour, kilometers per second, yards/feet per second, and knots. The results are provided in meters per second squared and standard gravity units (g). This versatile acceleration calculator accommodates various vehicles and objects, including cars, buses, trains, bikes, motorcycles, planes, ships, spacecraft, projectiles, and more, thanks to its extensive support for different units. To compute the missing variable, you only need to input three out of the four parameters: acceleration, initial speed, final speed, and time (acceleration duration). The results are consistently presented in the squared form of the input unit (e.g., km/h^2), meters per second squared (m/s^2), and standard gravity units (gn or simply g). Additionally, this calculator is equally adept at calculating deceleration. By entering a reduced value for the final speed, it can determine, for instance, the deceleration needed to bring a vehicle to a complete stop within a specified duration or the braking distance for a vehicle decelerating at a given rate.

Verdict

The call

The clearest difference is in-app purchases: Acceleration Calculator at none against QR Wave's 1. Acceleration Calculator also leads on ads (none vs shown) and device support (3 vs 1). On price there is nothing between them.
