The uncia is a twelfth part of the 'pes,' which is the Roman 'foot -' our word inch is also derived from 'uncia.' The Romans used the same word for ounce, which they measured using a technique taken from the Arabs.įor the Arabs, a silver Dirhem was determined by 45 full grown barley grains. Their basic unit of weight was the 'uncia,' from which the English word 'ounce' is originally derived. The Greeks used the same weight measurement as the Babylonians, but the Romans changed it. It was equal to the amount of water that filled an amphora (a kind of vase). The Babylonians invented the talent, as the basic unit of weight, and, based on their sexagesimal (60-based), divided into equal parts in terms of that number. For instance, the "carat," still used as a mass unit for gems, is derived from the carob seed. With the development of scales as a means of weighing, seeds and stones served as standards. These were filled with plant seeds that were then counted to measure the volumes. Why We Have Different Ways to Measure Weight?Įarly Babylonian and Egyptian records, as well as the Bible, indicate that weight was originally measured by the capacities of containers such as gourds or clay or metal vessels. depending on the exactness you want) to get the number of 16th's ounces:Ĭ) Take the integer part int(3.2) = 3. This is the fractional part of the value in ounces.ī) Multiply 0.2 times 16 (it could be 2, 4, 8, 16, 32, 64.

The previous step gave you the answer in decimal ounces (11.2), 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 11, the number of whole ounces, from 11.2:ġ1.2 - 11 = 0.2. Step 3: Convert from decimal ounces to a usable fraction of ounce Obviously, this is equivalent to 3.5 kilograms. So, 7.7 pounds = 7 pounds and 11 ounces (when rounded). Thus,ħ.7 pounds = 7 + 0.7 pounds = 7 pounds + 0.7 × 16 ounces = 7 pounds + 11.2 ounces. This works because one pound equals 16 ounces. So, take everything after the decimal point (0.7), then multiply that by 16 to turn it into ounces. Step 2: Convert the decimal part in pounds to ouncesĪn answer like "7.7 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 poundsģ.5 × 1 kilogram = 3.5 × 2.2 pounds (rounded), orģ.5 kilograms = 7.7 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.
