Introduction To Speed Calculator:

Whether you’re cruising in your new car or going for a jog, determining average speed is essential. This speed calculator aids in finding the average speed of a moving object based on the distance traveled and time taken. In this article, we explore the average speed formula, types of speed, and interesting speed-related facts.

Speed, Distance, Time: Speed, a concept rooted in physics, is associated more with moving objects than scientific equations. It’s our perception of how quickly we travel. Speed is measured in various units, such as km/h, mph, m/s, or knots. The fundamental idea of speed is the distance traveled per unit of time.

Types of Speed: Speed isn’t a precise term; there’s instantaneous speed (at a specific moment), average speed (total distance over time), and rotational speed (revolutions per unit time). Average speed is the focus here, calculated as total distance divided by total time.

Average Speed Formula: The formula for average speed is straightforward: average speed = total distance / total time. Units can vary, commonly in km/h, mph, m/s, or ft/s.

Using the Speed Calculator:

  1. Determine the distance traveled.
  2. Input the time taken.
  3. Get the average speed instantly.

Advanced mode: Compare time differences at alternative speeds.

Average Speed vs. Average Velocity: Speed is scalar, indicating only magnitude. Velocity, a vector, includes direction. While speed tells you how fast, velocity adds the aspect of directional change.

Curious Speed Facts: Explore intriguing speed-related facts:

  • Light speed is around 300,000 km/s.
  • Sound travels at 343 m/s (767 mph).
  • Cheetahs reach speeds up to 58 mph.
  • Usain Bolt recorded a speed of 27.44 mph.


  • Is velocity the same as speed? Velocity includes direction; speed is magnitude only.
  • Most economical driving speed? Generally around 50 mph.
  • Can Google Maps tell my speed? Yes, for Android users.
  • Convert mph to seconds? Divide speed by 60 twice.

Types of Speed (FAQ): Speed, velocity, acceleration, constant speed, variable speed, average speed, and instantaneous speed are different types of speed.

Unit for Speed: The base unit is meters per second, but common units include km/h, mph, and knots.

Converting mph to kph: Multiply mph by 1.6, or for kph to mph, multiply by 0.62.

Finding Final Speed: For average and initial speed, multiply average speed by 2 and subtract the initial speed. Alternatively, with initial speed, acceleration, and time, calculate acceleration times time, add the initial speed.

Formula for Average Speed: The most common formula is distance divided by time. If you have initial and final speed, add and divide by 2.

Types of Acceleration: Average and instantaneous acceleration are the two types, defining how an object’s movement changes over time.


Understanding speed is essential in various contexts. Whether driving, running, or exploring intriguing facts, this comprehensive guide simplifies the concept of speed and its calculations.
