Toggle for Metric Dimensioning

I am using Autocad 2000. I know, I am like an old dog who gets comfortable by the fireplace, and is happy with what I have.

Please someone tell me where the toggle is to set the dimensioning for metric dimensions. I have seen it in a couple of places and after I set it for millimeters, for some reason it still dimensions in English measurements. It's more than clear that I don't know what I am doing. If someone could help me, I'd appreciate it.

thank you,

gotchy

You have used the UNITS command?

Are you also using a metric template?

'English measurements' - don't the British use the Metric system though?

Format -> Dimension Style -> Select the dimension style of your dimensions and then change the units in the Primary (and if you want, Alternate) Units tabs

Thank you Gentlemen!
