Q&A for How to Convert Within Metric Measurements

There are exactly 100 centimeters (cm) in 1 meter (m). Therefore, 30 meters equals 3000 centimeters, 25 centimeters equals 0.25 meters, etc.

Multiply ounces by 28.35.

No, they are multiples of each other. Ten millimeters is a centimeter, a hundred centimeters is a meter, and a thousand meters is a kilometer. You can use these relationships to convert any number of one unit to the appropriate number of a larger or smaller unit

1 meter = 3.28 feet.

The easiest way is to use a conversion table.

5 centimeters = 5 x 0.3937 inch = 1.9685 inches.

Each centimeter equals 0.3937 inch.

Use division when converting a smaller unit to a larger unit. For example, when converting centimeters to meters, divide the number of centimeters by 100.

33.8.

A km is 100x larger than a cm - the metric system works in measures of 10. Move the decimal to the left 2 places (10 x 10 = 100).

Considering 1 km is 1,000 m, it'll be 1,000,000 mm. So you would multiply the number of km by 1,000,000.

Half a millimeter is 500 micrometers (or microns).

Divide the number of millimeters by one-million to get the corresponding number of kilometers. In other words, there are one-million millimeters in one kilometer.

You cannot convert a unit of weight/mass (such as a gram) to a unit of length (such as a kilometer).

1,000.
