What Are the Common Units of Length? Understanding measurement is an important part of mathematics. Every object has a set of dimensions that determines its shape and size. One measurement is the length that you can measure using your ruler. The length determines how long or short an object is. You must understand that when you measure length, you figure out two things. One is the number that determines the size of an object and a word that describes the measurement. Numbers without units hold no meaning, and that is why we use units of measurement that give a number meaning. There are four common units of measurement for length, and these include millimeter, centimeter, meter, and kilometer. Millimeter - The smallest unit for measuring length is a millimeter, and its abbreviation is mm. It is used for measuring something as small as a plant seed. Centimeter - A unit larger than a millimeter is centimeter. The abbreviation of the centimeter is cm. There are 10 millimeters in one centimeter. Meter - A unit larger than centimeter is meter, and its abbreviation is m. One meter is equal to 100 centimeters. Kilometer - The longest unit of measuring length is kilometer, and the abbreviation for kilometer is km. One kilometer is equal to 1000 meters. These worksheets help students identify measures and their units in word problem form.
