FutureStarrMiles Per Hour Calculator OR
Miles per hour is a unit of speed equal to the length of one statute mile in one hour. The inverse unit is metres per hour, metres per hour is a unit of speed equal to the length of one metre in one hour.
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). On the other hand, physicists most often use the SI base units which are meters per second (m/s). 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.You are driving along the long, open highway. You glance down at the speedometer of your car; it reads 100 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.g., in an hour).
In order to use the above speed, distance & time calculator, or do such math on your own, you will need to know two out of three metrics: speed, distance, time. You will need to convert the metrics to the same time and distance units, e.g. miles, kilometers, meters, yards, feet, and hours, minutes or seconds. For example, if you have speed in mph (miles per hour), time should also be in hours. If you have distance in kilometers, then speed should also be in km/h (kilometers per hour). where d is the distance travelled, v is the speed (velocity) and t is the time, so you can read it as Time = Distance / Speed. Make sure you convert the units so both their distance and time components match, or use our trip duration calculator above which will handle conversions automatically. For example, if you have distance in miles and speed in km/h, you will need to convert speed to mph or distance to kilometers. The time unit of the result will match the time unit of the speed measure, so if it is measured in something per hour, the result will be in hours. If it is measured in some unit per second, the result will be in seconds.Our Miles Per Hour Calculator can tell you how many miles you drive in a single stretch. On long road trips, knowing how many miles you are averaging per hour can give you an idea of how long it will take to get to your destination. It is also a good indicator if you are taking too many breaks or if traffic has caused delays in your journey. Knowing this information gives you the chance to drive further or a bit faster to make up time and distance. (Source: www.calculatorpro.com)
