"Unorthodox" number notations 4p7 + 1R2 : NewRPL thread spinoff.

Finally managed to get a copy of the IEC 60062 intl. std.

It distinguishes between quantities in Ohms and in Farads. For resistances (Ohms) it dictates the use of letters: L, R, K, M & G, with weights: \(10^{-3}\), \(10^0\), \(10^3\), \(10^6\) & \(10^9\) respectively. Such letters are used instead of the decimal dot/comma. L meaning \(10^{-3}\) is justified in such std. (instead of m) cause it dictates the use of uppercase letters, and M is already used for \(10^6\).

For capacitances (Farads), the letters used are: p, n, \(\mu\), m & F, with weights: \(10^{-12}\), \(10^{-9}\), \(10^{-6}\), \(10^{-3}\) & \(10^0\) respectively. As with the previous case, such letters replace the decimal dot/comma. \(\mu\) can be replaced by u or even U.
