Q&A for How to Understand the Metric System

Centimeters. Remember, 100 centimeters make a meter. So if you are 176 centimeters, for example; you are 1.76 meter(s) tall.

The speed is measured in kilometers per hour, as opposed to miles per hour. You'd have to multiply a car's speed in MPH by 1.6 to get its speed in kilometers, as a mile is 1.6 kilometers.

Divide millimeters by 304.8.

1 inch is 2.54 centimeters; but you can just multiple 1 inch by 2.5 with a tiny error rate.

Multiply by 100. The root "centi" means 100. (There are 100 cents in a dollar if that helps.) The root "milli" means 1000. Centimeter = 1/100 of a meter. Millimeter = 1/1000 of a meter.

There are 1,000 microliters in one milliliter.

25.4.

1,609.34.

1 inch is 25.4 mm. Divide the number of mm by 25.4 to get the number of inches.

100 centimeter = 1 meter 100 meter = 1 kilometer Therefore: 100x100. 1 kilometer = 100,000 centimeters

You multiple the kilogram by 1,000 milliliters. For example: 75 kg * 1,000ml = 75,000ml.

Multiply by 1,000,000 (one million). The prefix 'micro' means 'one millionth,' so a micromole is a millionth of a mole, which means there are 1,000,000 micromoles in a mole.

If 1 mile is 1609.34 meters, 3 miles is 4828.02 meters (1609.34 meters × 3 miles).

That's right.

Approximately 3.28.

To get centimeters, multiply meters by 100.

There are 1,000 micrograms in a milligram.

A comfortable room temperature = 20ºC = 293 K = 68ºF. A chilly temperature = 5ºC = 278 K = 41ºF. A warm temperature is the same as the room temperature. At the extremes, -40ºC = 233 K = -40ºF and 54ºC = 327 K = 130ºF are both quite dangerous levels inside and out unless you have alleviating factors (like cooling, heating, clothing, water, awnings, etc.).

Divide pounds by 2.2.
