Formulas
Speed Formula
Speed = Distance ÷ Time
Example: 100 km ÷ 2 hours = 50 km/h
Distance Formula
Distance = Speed × Time
Example: 60 mph × 3 hours = 180 miles
Time Formula
Time = Distance ÷ Speed
Example: 200 km ÷ 80 km/h = 2.5 hours

About Speed, Distance & Time
Speed, distance, and time are fundamentally related. If you know any two of these variables, you can calculate the third using simple formulas.
Units
- Metric: kilometers (km), kilometers per hour (km/h)
- Imperial: miles, miles per hour (mph)
- Science: meters (m), meters per second (m/s)
Conversions
- 1 mile = 1.609 kilometers
- 1 kilometer = 0.621 miles
- 1 mph = 1.609 km/h
- 1 km/h = 0.621 mph

How do I convert km/h to mph?
Multiply km/h by 0.621. For example: 100 km/h × 0.621 = 62.1 mph. Or divide mph by 1.609 to get km/h.
What's the difference between speed and velocity?
Speed is scalar (magnitude only). Velocity is a vector (has both magnitude and direction). Speed asks "how fast?", velocity asks "how fast and which way?"
How accurate are these calculations?
These formulas assume constant speed. In reality, speed varies due to traffic, terrain, weather, etc. Results are estimates for planning purposes.
Can I use this for flight calculations?
Yes, but remember airspeed differs from ground speed due to wind. These calculations work for ground speed only.
What if speed isn't constant?
Use average speed. For varying speeds, calculate each segment separately and sum the times or distances.
