How do i calculate kph

Let's consider the differences between instantaneous speed , average speed and rotational speed. For the purpose of two first, we will try to visualize it with an example of driving a car.

You are driving along the long, open highway. You glance down at the speedometer of your car; it reads kilometers per hour. From this, you know how far you will drive if you keep the speed constant. We know that, in practice, keeping the speed exactly constant is almost impossible although, on a highway with cruise control, it is nearly possible , and our speed fluctuates all the time, more or less. The actual distance you travel in an hour is the average of all these speeds.

Conclusion - the average speed is the total distance traveled in a unit of time e. So, what does the number your speedometer indicates really mean? That is your instantaneous speed; your speed at this exact moment. The rotational speed is a slightly different term, related rather to rotating objects than to objects that change their position in space. Accordingly, the rotational speed is the number of complete revolutions that object makes in a unit of time. We will not focus more on this topic because it is not the aim of this speed distance calculator.

If you would like to find out more about the topic of angular speed, go to our angular acceleration calculator or the rational kinetic energy calculator. Since the main purpose of this calculator is to calculate average speed, let's take a more in-depth look at this topic.

Average speed is measured in units of distance per time, and the average speed formula looks like this:. In our mph calculator the default unit is mph kph for metric-units countries , but you can change between any of the common units. Using this speed distance calculator is really easy, and you will get your result immediately. Check the points below to learn how to use this calculator properly:. You can also click the advanced mode button, you will access the extra functionality of this average speed calculator.

Here, you can compare what the difference in time will be if the object was traveling at another average speed a positive value if the object is traveling for a longer time and a negative value if the object is traveling for a shorter time. Speed and velocity might seem to be the same thing, but they're not. Speed is a scalar quantity - it is defined by magnitude only. In simple terms, it tells you how fast an object is moving.

On the other hand, velocity is a vector - it is defined not only by magnitude but also by direction. It tells you the rate at which an object changes its position. Imagine you drove a car meters forward and then meters back.

You would drive at a certain average speed in each direction, but you would have zero average velocity, as velocity is measured as the rate at which the position of the car changes, and, overall, the car didn't change its position.

Therefore, it is enough to say that the average speed of a car was 50 mph, but when calculating velocity we would have to add direction, let's say 50 mph east. And if you would like to know how fast your speed or velocity was changing you would need to calculate acceleration.

Do you have a need Take a look at some interesting facts and striking numbers in case of the speed of different objects and animals! Nothing can go faster than the speed of light, even if we take into account that speed is a relative measurement. Light moves at the speed of meters per second, what approximately gives kilometers per hour or miles per second. The time it takes for the light from the Sun to reach the Earth is around 8 minutes.

Sound moves through the air at a speed of around meters per second, which is It means that a sound wave in air needs about 2. In , Austrian Felix Baumgartner broke the sound barrier with his body!

He reached the speed of To put it into context, the typical passenger of jet aircraft cruises at an attitude of 33 - 35 feet, at a speed of around mph depending on the aircraft type as well as on the wind speed. You've probably heard that the fastest animal on the land is the cheetah, and it is true. Its maximum speed is really incredible, and, according to the latest research, it can reach speeds of up to 58 mph! Another amazing example is the peregrine falcons.

They can reach speeds exceeding In water, the fastest animal is the atlantic sailfish - 68 mph in water. What about people? Sprinter Usain Bolt is the fastest man ever in recorded history, with a recorded speed of This is a unit of speed and is an abbreviated form of meter per second. Speed means distance divided by time.

It defines the number of kilometers traveled in one hour and is read as 'kilometer per hour'. Learn Practice Download. Important Topics. Metric Conversion Chart.
