Coincidence, maybe, but convenient. That currently may be the case that many or most engineers rarely use both. But, from a historical perspective, when power generation and distribution were new, there was probably not…
When f is 60Hz, it makes for some nice round numbers, and easier for mental calculations. ω=2πf At 60Hz, ω is 376.99... very near to the integer 377. Also, Z₀, impedance of free space is not far off at 376.73... Ω
