Or, you can find the single factor you need by dividing the A factor by the B factor. For example, to convert from miles per hour to kilometers per hour you would multiply by 0. Or, multiply by 0. Lide, David R. Wikipedia contributors. Wikipedia, The Free Encyclopedia, last visited 26 Jun. Of course, having a GPS reading of the distance would be more precise.
Then you need to know the travel time. Make sure you subtract any rests or stops you made from the total trip duration. If you'd like to cite this online calculator resource and information as provided on the page, you can use the following citation: Georgiev G. Calculators Converters Randomizers Articles Search. Time Duration. Share calculator:. It is also the magnitude of velocity. Velocity, a vector quality, must have both the magnitude and direction specified, e.
There are a few other things you can do to maximise efficiency, however. First, try to maintain a constant speed , this will make your engine run as efficiently as possible - use cruise control on flats if you have it.
Second, drive at the highest possible gear within the speed limit , this again helps your engine run as economically as possible. Other tips include turning off AC and having as little weight in your car as you can.
Google Maps can tell you your speed, it has an inbuild speedometer , which is only currently for Android users. The unit for speed is distance over time , as it is defined as the amount of time it takes an object to cover a particular distance. The base, or SI, unit is metres per second , but this is not very practical in everyday life.
You are likely more familiar with units such as kilometres per hour, miles per hour and knots. Any distance over time is a speed unit, so other units of speed include nanometres per fortnight, Boeing s per solar year, or bananas per Friedman. Take a number, the next one in the sequence is the kilometres if the previous one was miles e.
The most common formula for average speed is distance traveled divided by time taken. The other formula, if you have the initial and final speed , add the two together, and divide by 2.
There are two types of acceleration, average and instantaneous. Average acceleration is the change in speed divided by the change of time , and is the how an object's movement changes with time, on average.
Instantaneous acceleration is the derivative of speed with respect to time , or the limit of the average acceleration over an infinitesimal period of time.
It is used to find the exact acceleration of an object at a particular time. Embed Share via. Table of contents: Speed, distance, time How fast am I going? Average speed vs average velocity Speed of sound - curious speed related facts FAQ. Speed, distance, time We have all heard of speed , but how confident are you in your understanding of this concept? How fast am I going? Average speed formula Since the main purpose of this calculator is to calculate average speed, let's take a more in-depth look at this topic.
Speed calculator - how to find your average speed? Check the points below to learn how to use this calculator properly: First, you need to determine the distance. This might be, for example, the distance you have driven from home to another city. Input this into the appropriate field. Now, there is a need to determine the time it took to cover a certain distance. Input this into the calculator. And here it is, you'll get the average speed.
Average speed vs average velocity Speed and velocity might seem to be the same thing, but they're not. Speed of sound - curious speed related facts Do you have a need FAQ Is velocity the same as speed?
What is the most economical driving speed? Can Google Maps tell me my speed? The symbol for miles per hour is mph.
There are 0. Kilometers per hour is a unit of Speed or Velocity in the Metric System. It measures the number of kilometers traveled in an hour. There are 1. Let's take a closer look at the conversion formula so that you can do these conversions yourself with a calculator or with an old-fashioned pencil and paper.
