A field level (or root-power level) is a logarithmic quantity used to measure quantities of which the square is typically proportional to power (for instance, the square of voltage is proportional to power by the inverse of the conductor's resistance), etc., with commonly used units neper (Np) or decibel (dB).
I Was Sold Dirt Cheap, But My Power Level Is Off the Charts (Japanese: クラス最安値で売られた俺は、実は最強パラメーター, Hepburn: Kurasu Saiyasune de Urareta Ore wa, Jitsu wa Saikyō Paramētā) is a Japanese light novel series written by Ryoma.
Power level may refer to: Level (logarithmic quantity), logarithm of the ratio of the value of some quantity to a reference value of the same quantity. Sound power level; The act of power-leveling in video games. The numerical rating of a character's strength and fighting ability in the Dragon Ball franchise, as in the quote and meme "It's Over ...
An example of the relationship between sample size and power levels. Higher power requires larger sample sizes. Statistical power may depend on a number of factors. Some factors may be particular to a specific testing situation, but in normal use, power depends on the following three aspects that can be potentially controlled by the practitioner:
That is, a change in power by a factor of 10 corresponds to a 10 dB change in level. When expressing root-power quantities, a change in amplitude by a factor of 10 corresponds to a 20 dB change in level. The decibel scales differ by a factor of two, so that the related power and root-power levels change by the same value in linear systems ...
A 3 dB increase in level is approximately equivalent to doubling the power, which means that a level of 3 dBm corresponds roughly to a power of 2 mW. Similarly, for each 3 dB decrease in level, the power is reduced by about one half, making −3 dBm correspond to a power of about 0.5 mW.
