The avoirdupois ounce (the common ounce) is defined as exactly 28.349523125 grams and is equivalent to one sixteenth of an avoirdupois pound. Ounceĭefinition: An ounce (symbol: oz) is a unit of mass in the imperial and US customary systems of measurement. Standards on the nutrition labels of food products often require the relative contents to be stated per 100 grams of the product. For example, the gram is typically used to measure non-liquid ingredients used for cooking or groceries. The gram was later redefined as one thousandth of a kilogram, the SI (meter-kilogram-second system of units) base unit of mass.Ĭurrent use: The gram is widely used in every life as well as scientific contexts. The gram used to be a fundamental unit of mass as part of centimeter-gram-second systems of units up until the widespread adoption of SI, which uses kilograms as the base unit of mass. History/origin: Originally, a gram was defined as the absolute weight of pure water in a cubic centimeter at the temperature of melting ice (later 4 ☌). Since 2019, the definition of the kilogram is no longer based on the international prototype, and rather is based on Planck's constant, h, along with the new definitions of the second and the meter. The definition of the gram is based on the kilogram, where a gram is one thousandth of a kilogram, the SI base unit of mass. This is the number of 16th's of a pound and also the numerator of the fraction.įinalmente, 4.2 quilogramas = 9 pounds 3 13/ 16 ounces.Definition: A gram (symbol: g) is a unit of mass in the International System of Units (SI). depending on the exactness you want) to get the number of 16th's ounces:Ĭ) Take the integer part int(13.44) = 13. This is the fractional part of the value in ounces.ī) Multiply 0.84 times 16 (it could be 2, 4, 8, 16, 32, 64. The previous step gave you the answer in decimal ounces (3.84), but how to express it as a fraction? See below a procedure, which can also be made using a calculator, to convert the decimal ounces to the nearest usable fraction:Ī) Subtract 3, the number of whole ounces, from 3.84:ģ.84 - 3 = 0.84. Step 3: Convert from decimal ounces to a usable fraction of ounce Obviously, this is equivalent to 4.2 kilograms. So, 9.24 pounds = 9 pounds and 3 ounces (when rounded). This works because one pound equals 16 ounces. So, take everything after the decimal point (0.24), then multiply that by 16 to turn it into ounces. Step 2: Convert the decimal part in pounds to ouncesĪn answer like "9.24 pounds" might not mean much to you because you may want to express the decimal part, which is in pounds, in ounces which is a smaller unit. Step 1: Convert from kilograms to poundsĤ.2 × 1 kilogram = 4.2 × 2.2 pounds (rounded), orĤ.2 kilograms = 9.24 pounds. Once this is very close to 2.2 pounds, you will almost always want to use the simpler number to make the math easier. If you need to be super precise, you can use one kilogram as 2.2046226218488 pounds. One kilogram is a unit of mass (not weight) which equals to approximately 2.2 pounds.
