![]() The changes were intended to improve the definitions of SI base units, not to actually change how the units are used throughout the world. Even though the definition of the kilogram was changed in 2019, the actual size of the unit remained the same. The meter and the second are defined in terms of c, the speed of light, and cesium frequency, Δ νCs. It is currently defined based on the fixed numerical value of the Planck constant, h, which is equal to 6.62607015 × 10 -34 in the units of J Kilogramĭefinition: A kilogram (symbol: kg) is the base unit of mass in the International System of Units (SI). The UK also often uses both pounds and stones when describing body weight, where a stone is comprised of 14 pounds. Many versions of the pound existed in the past in the United Kingdom (UK), and although the UK largely uses the International System of Units, pounds are still used within certain contexts, such as labelling of packaged foods (by law the metric values must also be displayed). This convenience could be the reason that the system was more popular than other systems of the time that used 10, 12, or 15 subdivisions.Ĭurrent use: The pound as a unit of weight is widely used in the United States, often for measuring body weight. This prototype weight could be divided into 16 ounces, a number that had three even divisors (8, 4, 2). It is a system that was based on a physical standardized pound that used a prototype weight. It was updated to its current form in 1959. The avoirdupois system is a system that was commonly used in the 13 th century. History/origin: The pound descended from the Roman libra, and numerous different definitions of the pound were used throughout history prior to the international avoirdupois pound that is widely used today. The avoirdupois pound is equivalent to 16 avoirdupois ounces. The international avoirdupois pound (the common pound used today) is defined as exactly 0.45359237 kilograms. The VBA code uses the CONVERT function to convert from one measurement unit to another and uses the VLOOKUP function to lookup the correct unit abbreviations (kg, g, lbm, ozm, etc.) stored on the second worksheet.Definition: A pound (symbol: lb) is a unit of mass used in the imperial and US customary systems of measurement. Enter a number and select the correct mass units.Įxplanation: the unit converter uses worksheet change events to automatically execute VBA code when you change a cell (B2, B4, B5, E4 or E5). Select Mass from the category drop-down list.Įxplanation: because you selected Mass from this drop-down list, the dependent drop-down lists in cell B5 and cell E5 now contain mass units.Ħ. You can also use the CONVERT function in Excel to convert from lbs to kg.ĭownload our free unit converter to quickly and easily convert from kg to lbs (or vice versa).ĥ. The unit abbreviation lbm stands for pound mass.Ĥ. Note: the CONVERT function has three arguments (number, from_unit and to_unit). You can also use the CONVERT function in Excel to convert from kg to lbs. To convert from lbs to kg, divide by 2.20462.ģ. ![]() The simple formula below does the trick.Ģ. First, to convert from kg to lbs, multiply by 2.20462.
