Measurement
Unit Conversion
Unit conversions involve changing measurements from one unit to another, typically within the same system of measurement. For example, converting from meters to kilometers or from milliliters to liters in the metric system. Conversion factors are used to facilitate these changes. The metric system is particularly convenient because all units are based on powers of ten, making conversions relatively simple. For instance, a liter is 10 times larger than a deciliter.
Metric System
The metric system is an international system of measurement based on the decimal system. It uses seven fundamental units for measuring physical quantities: meter for length, kilogram for mass, ampere for electric current, kelvin for thermodynamic temperature, mole for amount of substance, candela for luminous intensity, and second for time. Each of these units is defined in terms of practical applications and is universally recognized.
Time Conversions
Time can be measured using seconds, minutes, hours, days, weeks, months, and years. In the metric system, the basic unit of time is the second, which can be converted to higher or lower units simply by adding or removing zeros. For example, 300 seconds is equal to 5 minutes. Additionally, time can be measured in equivalent non-SI units like hours, days, weeks, months, and years. These conversions can be done easily using the metric system's base of ten.
