How many fans does 1.6K have?

1.6k is 1600 fans. Because k is the abbreviation of kilo, which means "thousand" or monetary unit, and can also be expressed as bytes or temperature, 1k can mean 1000 fans. In our daily life, we can often see that the salary of the recruitment position is expressed as 5000 K ~ 8000 K in the recruitment advertisement, so "K" is used as the monetary unit here.
