What year?

Are they twin or single chamber forks?

For single chamber, it's measured by height and the amount of oil that goes in varies...

For dual chamber I believe it's 300cc's for the outer and the inner is measured by height as well.

- Do you mean millimeters or milliliters ? One is a measurement for distance, the other a measurement for liquid, I'd assume you meant milliliters ?

I'm 210 Lbs without gear and I run 355 - 360 millileters of fork oil in each outer chamber ('09 yz450f).

On a side note I've got Diverse Suspension Products fork and shock springs for my weight and they're awesome.

That fork is a single chamber, open bath fork, not at all different than the WR for that year. It will take just over a quart to fill it. With the spring removed and both the damper and main tubes collapsed, fill the fork to the holes in the inner tube. Pump the air out of the dampers, then fill the fork until the oil level is 110mm below the top of the collapsed tubes.
