Speed Analysis Tool
Speed Calculator
Calculate speed, distance, or time using the fundamental relationship: speed = distance / time
Derived formulas:
• d = v × t (distance = speed × time)
• t = d / v (time = distance / speed)

Frequently Asked Questions
Common questions about speed calculations
What is the formula for speed?
The speed formula is: Speed = Distance / Time (or v = d / t). For example, if you travel 100 kilometers in 2 hours, your speed is 100 / 2 = 50 km/h.
How do I convert mph to km/h?
To convert miles per hour (mph) to kilometers per hour (km/h), multiply by 1.60934. For example: 60 mph × 1.60934 = 96.56 km/h. Use our speed converter for instant conversions.
What's the difference between speed and velocity?
Speed is a scalar quantity that measures how fast you're moving, while velocity is a vector that includes both speed and direction. This calculator measures speed only.
How accurate is this speed calculator?
Our speed calculator uses precise conversion factors and formulas to provide accurate results. It supports 9 distance units (millimeters to nautical miles) and 6 speed units for maximum flexibility.
Understanding Speed
Speed is a scalar quantity that refers to how fast an object is moving. It is the rate at which an object covers distance.
Average speed is calculated by dividing the total distance traveled by the total time taken. Unlike velocity, speed does not account for direction.
Example: A car travels 150 km in 2 hours. Its average speed is 150 / 2 = 75 km/h.
