I always thought Google was king :-)

I googled "what is middle c in scientific notation" and got.
Middle C (the fourth C key from left on a standard 88-key piano keyboard) is designated C4 in scientific pitch notation, and c′ in Helmholtz pitch notation; it is note number 60 in MIDI notation.

Here is the C Note Wiki

"Wiki SEE Wiki Do" or is that "Wiki C Wiki Do" :-)
