Where can I find a web page that describes resistor value designations?

I have a schematic that calls out a resistor value of 4K74. Is this 4.7K?
If so, what's the last "4" for? If it's not 4.7K, what is it?

4.74k but if it's calling for a 5 or 10% tolerance part there's no need to use a
close tolerance value.
