To determine how many miles per hour (mph) 20 kilometers per hour (kph) is, one must first understand the different measurement units used for speed. The metric system, which is the standard system of measurement used in most countries, measures speed in kilometers per hour, while the imperial system, which is used in countries such as the United States and the United Kingdom, measures speed in miles per hour. To convert from one system to another, one must use a conversion factor. In this case, we must use the conversion factor of 1.6 to convert from kilometers per hour to miles per hour.
One kilometer is equal to 0.62 miles, so to convert from kilometers per hour to miles per hour, one must multiply the speed in kph by 1.6. Therefore, 20 kph is equal to 12.4 mph. To summarize, 20 kph is equal to 12.4 mph, or 12 mph and 4/10ths of a mile per hour.
Understanding the Measurement of Speed
The measurement of speed is based upon the amount of distance traveled in a certain amount of time. The two most common units for measuring speed are kilometers per hour and miles per hour. A kilometer is a unit of distance equal to 1,000 meters, and a mile is equal to 1.6 kilometers. Therefore, one kilometer per hour is equal to 0.62 miles per hour.
Speed is measured using the formula speed = distance/time. This means that the speed of an object is determined by how far it travels in a certain amount of time. For example, if an object travels 1 kilometer in 1 hour, its speed is 1 kilometer per hour. Similarly, if an object travels 1 mile in 1 hour, its speed is 1 mile per hour.
Calculating Speed in Different Measurement Units
To calculate speed in different measurement units, one must first understand the conversion factor between the two units. For example, the conversion factor from kilometers per hour to miles per hour is 1.6. This means that to convert from kilometers per hour to miles per hour, one must multiply the speed in kph by 1.6. Similarly, to convert from miles per hour to kilometers per hour, one must divide the speed in mph by 1.6.
To calculate the speed of an object in a different measurement unit, one must first determine the speed of the object in the original measurement unit, then multiply or divide the speed by the conversion factor to get the speed in the desired measurement unit. For example, if an object travels at 20 kph, one can calculate its speed in mph by multiplying 20 by 1.6, resulting in a speed of 12.4 mph.
Examples of Conversions Between KPH and MPH
To further illustrate the conversion between kilometers per hour and miles per hour, here are some examples of common speeds in both measurement units:
- 10 kph = 6.2 mph
- 20 kph = 12.4 mph
- 30 kph = 18.6 mph
- 40 kph = 24.8 mph
- 50 kph = 31 mph
Using Speed Limits to Calculate KPH and MPH
Speed limits are a common way to measure speed in both kilometers per hour and miles per hour. For example, in the United States, the speed limit on highways is typically 65 mph, while in the United Kingdom the speed limit on highways is usually 70 mph. To convert between these two measurement units, one must multiply the speed limit in mph by 1.6.
For example, the speed limit of 65 mph in the United States is equal to 104 kph in the United Kingdom. Similarly, the speed limit of 70 mph in the United Kingdom is equal to 112 kph in the United States.
Other Uses of KPH and MPH
Kilometers per hour and miles per hour are also used to measure the speeds of vehicles, such as cars and bicycles, as well as the speeds of aircraft and boats. The speeds of these objects are typically measured using speedometers or other instruments that measure the speed of an object over a certain distance and time.
Kilometers per hour and miles per hour are also commonly used to measure wind speed. Wind speed is typically measured using an anemometer, which is an instrument that measures the speed of air flowing past it. Wind speeds are typically measured in both kilometers per hour and miles per hour.
