The width of a room may be expressed as about 5 meters (m), whereas a large distance, such as the distance between New York City and Chicago, is better expressed as 1150 kilometers (km). A smaller unit of volume that is commonly used is the milliliter (mL—note the capital L which is a standard practice). The Unit is meters × meters × meters, which is written m 3. Today we just turn on an instrument and read the depth to a high level of accuracy. Example 1: 10-6 kg = 1 mg (one milligram), but not 10-6 kg = 1 µkg (one microkilogram) Example 2: Consider the earlier example … Meter is the SI unit of length and is defined by taking the fixed value of the speed of light in vacuum.
