![]() However, the object’s mass would remain the same in both places because mass measures the amount of substance in an object. For this reason, an object’s weight would be different if it was weighed on Earth or on the moon because of the difference in the gravitational forces. Weight is a measure of the pull of gravity on an object. You may notice that the word “mass” is used here instead of “weight.” In the sciences and technical fields, a distinction is made between weight and mass. A regular-sized paperclip has a mass of about 1 gram.Īmong scientists, one gram is defined as the mass of water that would fill a 1-centimeter cube. The basic metric unit of mass is the gram. A meter is slightly larger than a yardstick, or just over three feet. In the metric system, the basic unit of length is the meter. So, what if you have to find out how many milligrams are in a decigram? Or, what if you want to convert meters to kilometers? Understanding how the metric system works is a good start. customary system-there are 12 inches in a foot, and 3 feet in a yard…and 5,280 feet in a mile! This idea of “10” is not present in the U.S. For example, a liter is 10 times larger than a deciliter, and a centigram is 10 times larger than a milligram. customary system of measurement, the metric system is based on 10s. These measurement units are part of the metric system. ![]() People in many countries use words like “kilometer,” “liter,” and “milligram” to measure the length, volume, and weight of different objects. If you travel to other countries, you will see that road signs list distances in kilometers and milk is sold in liters. In most other countries, the metric system is the primary system of measurement. ![]() customary measurement system and the metric system are used, especially in medical, scientific, and technical fields. ![]()
