Converting Ocular Unit Magnification

[Draco]

Hey guys, I'm in panic mode right now and was just hoping if you guys knew a bit about magnification? Well basically i did a lab and in the lab we were supposed to observe and measure pollen tube length at 40x. My partner didn't follow this and measured the lengths at different magnifications. I have the ocular units and magnifications and was just wondering is it possible to convert the ocular units to like different magnifications.

So like converting ocular units from 10x to 40x. (e.g. 25 OMU at 10x is ____ OMU at 40x)

Is it possible? Please help, I'm like really scared now.

pretty straightforward. See a description http://academic.evergreen.edu/curricular/fcb/wk2calibration.doc"
