What's more, a slow loading time also lessens chances they will return in the future. These findings dovetail with renowned research from cloud services provider Akamai. Its State of Online Retail Performance revealed that conversion rates decrease drastically as page load times increase.

Conversion rates continue to decline sharply from there. The bottom line: Bounce rate—the percentage of users that navigate away from a website after viewing only one page—increases significantly as the page load time goes up. If you want consumers to do business with you, you need to ensure your site loads as quickly as possible, especially on a mobile device. Which raises the question: how fast is fast enough? While site loading speeds have been dropping in recent years, visitors are still waiting too long for many mobile pages to render completely.

The new reality?

A mobile page must display content to consumers in one second or less. That's the golden standard businesses must meet or beat to reach and convert consumers high on expectation and low on patience, according to the Mobile Marketing Association in Germany MMA Germany and Google in Germany. To understand the state of site speed across the globe, 6 million domains across 55 countries including Germany were analyzed. On average, Retail posted loading times of 2.

Travel came in just behind, posting an average loading time of 3. Importantly, this iteration of the Mobile Speed Leaderboards looked beyond Germany's borders to compare mobile website loading times globally. One of those specifications is speed for uploads and downloads. Downloading is when you receive information sent from servers on the internet downloading apps, streaming movies and music, etc.

Uploading is when you send information to server on the internet sharing images over Facebook, uploading videos to YouTube , hosting your own website, etc. There's a minimum peak download rate and a minimum peak upload rate for a network to be called a 5G network , meaning that each 5G base station has to support speeds at least this fast:. Also remember that bits are not the same as bytes the above measurements are written in bits.

Because there are eight bits in every byte, to convert those 5G speeds into megabytes MB and gigabytes GB , you have to divide them by eight. Latency refers to the time lapse between when the cell tower sends data and when the destination device like your phone receives the data. For comparison, the latency on a 4G network might be around 50— ms, which is actually more than twice as fast as the older 3G network! The measurements listed above are a reflection of 5G speeds in ideal conditions with basically no latency or interference, and only if your device is the only one using that 5G cell.

Every 5G cell supports, at minimum, one million devices for every square kilometer. Download and upload speed is split equally between every device on the same cell. So, we can say that the human perception of speed is relative. Automobiles and trains measure speed in kilometers per hour kph or in miles per hour mph , and on airplanes and ships we usually use knots kn. The speed definition hides behind these units, and we can get familiar with it by examining them. Everything about speed is related to distance and time.

The units of speed are specified by traveled distance units divided by units of time, and that is the general idea of speed. In a more simple way - speed is the distance traveled per unit of time. Speed is not a precise term - there are a few more accurate meanings, and they should not be confused with each other. 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.

## Speed Calculator

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.

## How fast is the earth moving? - Scientific American

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
