Are you saying .482 is written somewhere, or that is the reading on your digital meter?

If you are using a digital meter, it should indicate whether its reading Megohms either with a symbol in the display or a knob setting.

I think using the decimal point (.482) would be odd for k ohms (it would just read 482 ohms), so this would be either ohms or megohms.
