A large motor winding with many turns around an iron core may have an inductance of scores or hundreds of henries. The physical size of an inductance is also related to its current carrying and voltage withstand ratings. Henry (unit) The henry (symbol: H) is the SI derived unit of electrical inductance. If a current of 1 ampere flowing through the coil produces flux linkage of 1 weber turn, the coil"

The International Bureau of Weights and Measures, which maintains the SI-standard, states that the physical unit and its symbol should not be used to provide specific information about a given physical quantity and that neither should be the sole source of information on a quantity. Nonetheless, colloquial English sometimes conflates the quantity power and its unit by using the non-SI unit watt-peak and the non-SI symbol W prefixed as within the SI, e.g. kilowatt-peak (kW), megawatt-peak (MW), etc. As such a photovoltaic installation may for example"

"Becquerel The becquerel (; symbol: Bq) is the SI derived unit of radioactivity. One becquerel is defined as the activity of a quantity of radioactive material in which one nucleus decays per second. The becquerel is therefore equivalent to an inverse second, s. The becquerel is named after Henri Becquerel, who shared a Nobel Prize in Physics with Pierre and Marie Curie in 1903 for their work in discovering radioactivity. As with every International System of Units (SI) unit named for a person, the first letter of its symbol is uppercase (Bq). However, when an SI unit is spelled out"

One zebibyte (1 ZiB) is equal to eight zebibits (8 Zibit). One thousand twenty-four zebibytes (1024 ZiB) is equal to one yobibyte (1 YiB).

This standard uses 'bit' as the symbol for bit, as opposed to 'b'. IEEE 1541 recommends: The ""bi"" part of the prefix comes from the word binary, so for example, kibibyte means a kilobinary byte, that is 1024 bytes.

This finding led to Maxwell's conjecture that light is an electromagnetic wave. This also led to Weber's development of his theory of electrodynamics. Also, the first usage of the letter ""c"" to denote the speed of light was in an 1856 paper by Kohlrausch and Weber. The SI unit of magnetic flux, the weber (symbol: Wb) is named after him.

As W represents the watt, the SI unit of power, this can lead to confusion, making the use of the correct Unicode code point preferable. Where the character set is limited to ASCII, the IEEE 260.1 standard recommends substituting the symbol Ohm for Ω. In the electronics industry it is common to use the character R instead of the Ω symbol, thus, a 10 Ω resistor may be represented as 10R. This is the British standard BS 1852 code.

"International System of Units The International System of Units (SI, abbreviated from the French "") is the modern form of the metric system, and is the most widely used system of measurement. It comprises a coherent system of units of measurement built on seven base units, which are the ampere, kelvin, second, metre, kilogram, candela, mole, and a set of twenty prefixes to the unit names and unit symbols that may be used when specifying multiples and fractions of the units. The system also specifies names for 22 derived units, such as lumen and watt, for other common physical quantities."
