How to Calculate Velocity
If you’re searching for “how to calculate velocity”, the most common formula is average velocity: distance divided by time.
Velocity Formula
Velocity (v) = Distance (d) ÷ Time (t)
Example
If you travel 100 meters in 10 seconds, v = 100 ÷ 10 = 10 m/s.
Frequently Asked Questions
What is the formula for velocity?
Velocity equals distance divided by time: v = d/t. For example, if you travel 100 meters in 20 seconds, your velocity is 100÷20 = 5 meters per second (m/s).
What is the difference between speed and velocity?
Speed is how fast something moves (scalar quantity). Velocity includes both speed AND direction (vector quantity). For example, 60 mph is speed. 60 mph north is velocity. Our calculator computes average velocity.
How do I calculate velocity from distance and time?
Enter your distance traveled and the time it took into the calculator. Select your preferred output units (m/s, km/h, mph, or ft/s). The calculator automatically applies the velocity formula and converts between units.
What units can I use for velocity?
The calculator supports: meters per second (m/s), kilometers per hour (km/h), miles per hour (mph), and feet per second (ft/s). You can input distance in any unit and get velocity in any of these units.
What is average velocity?
Average velocity is total displacement divided by total time. It represents the overall rate of motion, ignoring changes in speed during the journey. For constant speed, average velocity equals instantaneous velocity.
Can I calculate velocity for running or cycling?
Yes! Enter your distance (e.g., 5 kilometers) and time (e.g., 25 minutes), and the calculator shows your average velocity in multiple units. This is useful for tracking pace and comparing performance across different activities.
