For instance, there are 100 centimetres in one metre or 1000 grams in one kilogram. The newest and most used of the three systems is the metric system or SI system which use 10, 100 or 1000 of a smaller unit to make a bigger one. The number of smaller units that make the bigger units in these two systems varies: For example, there are 12 inches in a foot and 16 ounces in a pound. The older two, the British imperial system and the closely related US customary system use the foot as a measure of length, the pound as a measure for weight, and the second as a measure for time. Today, most units of measure fall into one of three systems: In the past, different units were used in different countries. Now scientists define the meter by using the speed of light. During that time, saying that something had a length of two meters meant that it was exactly twice as long as the rod used to define the meter. Before 1982, one meter was defined as the distance between two markers on a special metal rod. We can measure how big things are, how warm they are, how heavy they are, and many other features.įor example, the metre is a standard unit to measure length.
