How many meters are in 7.2 kilometers ?
The Correct Answer and Explanation is:
To convert kilometers into meters, you need to know the basic conversion factor: 1 kilometer (km) is equal to 1,000 meters (m).
So, to convert 7.2 kilometers to meters, you multiply: 7.2 km×1,000=7,200 m7.2 \, \text{km} \times 1,000 = 7,200 \, \text{m}7.2km×1,000=7,200m
Explanation:
The kilometer is a unit of length in the metric system. It is commonly used to measure longer distances, such as between cities or along highways. The meter, also a metric unit, is the base unit of length in the International System of Units (SI). To understand the relationship between kilometers and meters, it’s helpful to recognize that the metric system is built on powers of 10. Each unit in the metric system (meter, kilometer, millimeter, etc.) is 10 times larger or smaller than the next unit.
When converting from a larger unit to a smaller unit (like from kilometers to meters), you multiply by a factor of 10. In this case, since there are 1,000 meters in a kilometer, multiplying by 1,000 shifts the decimal point three places to the right.
In everyday scenarios, such as measuring the length of a road, a race, or a geographical distance, it’s common to encounter distances in kilometers. However, for more precise or smaller-scale measurements, meters are typically more practical.
For example, when a race or event is described as being 7.2 kilometers long, it might be helpful to know the equivalent distance in meters, especially for athletes, organizers, or scientific research, where precision is key. Hence, the conversion of 7.2 km to 7,200 meters allows for greater accuracy and consistency across various applications.
