Measurements and UnitsHow old are you? How tall are you? The answers to these questions are Measurements. Measurements are important in both science and everyday life. Hardly a day passes without the need for you to measure amounts of money or the passage of time. For a measurement to make sense, it requires both a number and a unit. For example, if someone tells you the store is “five” from the school, you would probably ask, “Five what? Five meters? Five blocks?” You typically describe a distance using standard units of measurement, such as meters, miles, or kilometers. By using units, you help other people understand exactly what your measurement mean. In your daily conversations with your peers and family, you use measurements to convey what you want them to understand. Measurements are distance, time, volume, density, mass, temperature, area, speed, acceleration, force, weight, electric current, energy, and etc.

 Units help you describe measurements. They make understanding measurements easy. Many of the units you are familiar with, such as inches, feet, and degrees Fahrenheit, are not units that are used in science. Scientists use a set of measuring units called SI, or the International System of Units. SI units started in France 1791. SI units include meter (m), gram (g), Kelvin (K), centimeter cube (cm3), and gram per centimeter cube (g/cm3).
