Voltage kV Why is k lowercase?

International standard units of measurement are generally in lower case. Only units with named names, such as volts V, amperes A, Kelvin K, and watts W, are capitalized in order to show respect for the scientist's predecessors, and the rest of the units that are not named after people are generally lowercase. This explains why V is capitalized.

Secondly, for quantifiers, the initial magnitude is generally lowercase. If the same letter is used, the case is often different orders of magnitude, such as Mω, Mω, lowercase m means 1×10-3; And capital M means 1×106. So k here means 1 times 103. It should be in lower case. (Perhaps this lowercase k is to distinguish it from K (Kelvin).) In summary, kV should be lowercase k and uppercase V.

For this problem, in fact, you can read all caps people can understand, mainly from the academic point of view, the national standard is how to use, we must write in accordance with the standard.

Power Scientist Senior

Volt V

Alessandro Volta, a famous Italian physicist who invented the Voltaic pile in 1800, died on March 5, 1827, at the age of eighty-two. In his honor, the unit of electromotive force was named the volt.

Ampere A

Andre Marie Ampere was a famous French physicist, chemist and mathematician. The international unit of electric current is named after Amperes because of his outstanding work on electromagnetism from 1820 to 1827, and he is known as the "Newton of electricity".

The standard symbol of the unit of measurement must be correct
