I think this is mostly a US thing. Why use yearly salary? You’re not paid once a year, are you? Most likely once a month. Referencing monthly salary makes much more sense.
“I’m making 50k”. Great, now I have to guess - dollars? Monthly? Yearly? If yearly then what’s the monthly paycheck? Net? Gross?
Guess? It’s called math. You want to know monthly? Divide by 12. You’re mad that you have to do math? It’s a standardized number.
For yearly to hourly divide by 2 and lop off 3 zeros. $35/hour = $70,000/year (approximately)
