Q&A for How to Convert Meters to Millimeters

Multiply by 1,000.

Divide mm by 1,000.

To answer, you need to convert all of these to the same unit of measurement, for example, mm. There are 1000 mm in 1 m, and 10 mm in 1 cm. So the problem changes to 1,000mm + 850mm + 400mm.

Divide by 1,000.

Since there are 1,000mm in 1 m, you need to divide 389 by 1,000. You can do this simply by moving the decimal point three places to the left. So 389mm becomes .389m.

There are 100 centimeters in 1 meter. To convert, divide the number of centimeters by 100.

Multiply the number of square meters by one million.

Divide by 1,000.

Multiply by one million (1,000,000).

There are fewer meters in a given length than there are millimeters. So when you convert any length from millimeters to meters, you're looking for a smaller number (because meters are longer than millimeters). So you divide, since division normally results in a smaller number - just as multiplying usually results in a larger number.

25 m ÷ 0.245 = 102, with a very small amount left over.

Multiply 9,003 by 1,000. You can do this simply by adding three zeros to the end of the number. This gives you 9,003,000mm.

There are 1,000 mm in a meter, so it's 6,020 mm.

There are 1,000 milliliters in a liter, so it's 2,000 ml.

Multiply the number of meters by 100.

Divide the number of mm by 1,000, so it's 42.108 meters.

Divide the number of millimeters by 10.

A millimeter is a measurement of length. A square millimeter is a measurement of area. One is not convertible to the other.

Divide the number of feet by 3.28 (or multiply by 0.3).

Multiply by 1,000.

Multiply 175 by 1000. That equals 175,000 mm.
