Speed Calculation Tips

  • Remember the basic formula: Speed = Distance ÷ Time
  • Make sure your units match (e.g., km with hours, miles with hours)
  • Convert minutes to hours by dividing by 60 (30 min = 0.5 hours)
  • For walking speed, average is about 5 km/h (3 mph)
  • For driving, highway speeds are typically 100-120 km/h (60-75 mph)

Why Speed Calculations Matter

Speed calculations help us understand how fast objects move, plan travel times, and compare different modes of transportation. Whether you’re driving, running, or just curious about how long a trip will take, speed calculations give you the answers.

Our calculator makes it easy to find speed, distance, or time using the simple relationship between these three measurements. Just enter two values and we’ll calculate the third for you.

Common Speed Questions

What’s the difference between speed and velocity?

Speed is how fast something is moving, while velocity is speed with direction. For example, “60 km/h” is speed, but “60 km/h north” is velocity. In everyday use, we usually just talk about speed.

How do I convert between different speed units?

To convert km/h to mph, multiply by 0.621. To convert mph to km/h, multiply by 1.609. To convert m/s to km/h, multiply by 3.6. Our calculator handles these conversions automatically.

What is average speed?

Average speed is the total distance traveled divided by the total time taken. It’s different from instantaneous speed, which is your speed at a specific moment. Our calculator gives you average speed.

How accurate are speed calculations for real trips?

Speed calculations give you theoretical times based on constant speed. Real trips have stops, traffic, and speed changes, so actual travel time may be longer. Use these calculations as estimates.

What’s a good walking speed?

Average walking speed is about 5 km/h (3 mph). This can vary based on fitness, terrain, and whether you’re carrying anything. Running speeds are typically 8-15 km/h (5-9 mph).
