A Velocity Calculator is a physics tool that computes the rate of change of position of an object — how fast it moves in a specific direction. Velocity is a vector quantity, meaning it has both magnitude (speed) and direction.
The fundamental formula is v = d ÷ t, where v is velocity, d is displacement, and t is time. This calculator converts all inputs to SI base units (meters and seconds) before computing, then outputs results in m/s, km/h, mph, ft/s, and knots simultaneously.
Whether you are a student solving physics problems, an engineer analyzing motion, or a sports analyst measuring performance, this tool delivers instant, accurate results across all common unit systems.
Velocity equals displacement divided by time. This gives the average velocity over the entire time interval. The SI unit is meters per second (m/s).
| Displacement | Time | Velocity (m/s) | Velocity (km/h) |
|---|---|---|---|
| 100 m | 10 s | 10 m/s | 36 km/h |
| 240 km | 2 h | 33.33 m/s | 120 km/h |
| 5 mi | 30 min | 4.47 m/s | 16.09 km/h |
| 1,500 m | 5 min | 5 m/s | 18 km/h |
| 100 ft | 2 s | 15.24 m/s | 54.86 km/h |
| 1 km | 1 min | 16.67 m/s | 60 km/h |
| m/s | km/h | mph | ft/s | knots |
|---|---|---|---|---|
| 1 | 3.6 | 2.237 | 3.281 | 1.944 |
| 5 | 18 | 11.18 | 16.40 | 9.72 |
| 10 | 36 | 22.37 | 32.81 | 19.44 |
| 30 | 108 | 67.11 | 98.43 | 58.32 |
| 100 | 360 | 223.69 | 328.08 | 194.38 |

Speed is a scalar quantity — it only has magnitude (e.g. 60 km/h). Velocity is a vector quantity — it has both magnitude and direction (e.g. 60 km/h north). This calculator computes the magnitude of average velocity, which equals average speed when motion is in a straight line.
The basic velocity formula is v = d ÷ t, where v is velocity, d is displacement (change in position), and t is time elapsed. The SI unit for velocity is meters per second (m/s).
Division by zero is mathematically undefined. If time equals zero, the formula v = d ÷ t has no valid result. In physics, instantaneous velocity at a single point in time requires calculus (the derivative of position with respect to time).
Yes. Negative displacement means the object moved in the opposite direction from the reference point. A negative velocity result indicates motion in the negative direction. This calculator supports negative displacement values.
Multiply m/s by 3.6 to get km/h. For example, 10 m/s × 3.6 = 36 km/h. This calculator performs all unit conversions automatically and displays results in m/s, km/h, mph, ft/s, and knots simultaneously.
