The unit for measuring the loudness of sound is the decibel. This unit is one-tenth of a Bel. The Bel was named in honor of Alexander Graham Bell, the inventor of the telephone and phonograph.


Power is measured in different ways depending on what type of power is being used. Electrical power is measured by the watt or joule. Other measurements of power include ergs per second, horsepower, metric horsepower and foot-pounds.


The scientific, international standard SI unit for measuring weight is the "Newton." In everyday use, the unit for mass, the pound (lb) or kilogram (kg), is used instead.


The unit that is used to measure force in the SI system of units is the Newton. One Newton is equal to 1 kilogram per meter squared. The standard symbol for Newton is N, and the unit is named after the physicist Isaac Newton, who derived the laws of motion.


Natural gas is measured in cubic feet, cubic meters, British thermal units or joules, while gasoline is measured in gallons, British thermal units, joules or metric tons. The unit used to measure gas is dependent upon the situation in which the gas is being used.


A common unit of measure for an object's mass is the metric unit grams. However, mass is often confused with weight, which are similar ideas but different characteristics of an object.


A measurement is a quantification of a dimension, such as length or weight, usually represented as a number of standardized units. The type of measurement used depends on the properties being examined.


Some of the standard units of measurements in the United States include feet, inches and miles for measuring length; pounds and ounces for measuring weight; and quarts, ounces and liters for measuring volume of liquid. In addition, temperature is usually measured using Fahrenheit degrees.


Some common units used for water measurements are ounce, fluid ounce, cup, pint and gallon. Other measurements are liter and milliliter. Fluid ounce and ounce are different because fluid ounce measures volume while ounce measures mass, but volume and mass are the same in the case of water.


Air pressure, the force exerted on a mass by the weight of air particles, is measured in either inches of mercury or in millibars, represented by inHg and mb, respectively. One standard atmosphere, represented by the symbol atm, is equal to 29.92 inHg, or 1013.25 mb.
