The symbols of the units named after scientist should be written by a capital letter. N•m, N m). Paris, France, May 20 – How we measure the world underwent a quantum leap on Monday as scientists adopted new hyper-accurate definitions for units of weight, electricity and temperature derived from the universal laws of Nature. Note that this is about writing the units fully! The . For example : N for newton, H for henry, W for watt . Conversion of units describes equivalent units of mass in other systems. kg to catti [China] kg to megatonne kg to hundredweight [short, US] kg to carat [pre-1913 US] What is the symbol for kilogram? Its symbol is ‘kg’. To make it more convenient for users and easier to use and remember, we often use notations/symbols to represent these physical quantities. In a compound unit symbol, multiplication is denoted by either a dot or a space (e.g. Stable Road Capital … The kilogram or kilogramme (symbol: kg) is the base unit of mass in the International System of Units (SI), and is defined as being equal to the mass of the International Prototype of the Kilogram (IPK, also known as "Le Grand K" or "Big K"), a cylinder of platinum-iridium alloy stored by the International Bureau of Weights and Measures at Saint-Cloud, France. The following table shows Unicode symbol, HTML code, CSS code, and official HTML name for the characters categorized under unit symbols. The litre, and the symbol lower-case l, were adopted by the CIPM in 1879 (PV, 1879, 41). It is important to note that the kilogram is the only SI unit with a prefix as part of its name and symbol. It is defined by taking the fixed numerical value of the Planck constant . However the raised dot, may be omitted in the case of familiar compound unit symbols. Please Note: Where symbols are used convention has it that they are always lower case letters except where the Base Unit is named after a person like Celsius (°C), Pascal (P) or Newton (N) and 16 other scientists. The large calorie, kilogram calorie, kilocalorie (symbol: kcal), or Calorie (capital C) is the amount of heat (energy) needed to increase the temperature of one kg of water by 1 °C, exactly 1000 small calories, or about 4.184 kJ.
