Unit syntax error, not sure why

This is likely something very obvious but I can't figure it out. I'm trying to define a variable:
omega0 = e_const*hbar_const*sqrt(fermienergy/W)
fermienergy has units joules and W has units of (micro)metres. W is the thing which varies in a parametric sweep. Any ideas why it gets oranged out and says "unit syntax error"?
I'm using the radio frequency module
omega0 = e_const*hbar_const*sqrt(fermienergy/W)
fermienergy has units joules and W has units of (micro)metres. W is the thing which varies in a parametric sweep. Any ideas why it gets oranged out and says "unit syntax error"?

Hello Joshua,
Mathematical functions like sqrt take scalar arguments. Hence the "oranging out", which means a warning, rather than an error.
If you know what you are doing, you can ignore it. Alternatively you can modify your expression to something like sqrt(const1*fermienergy/W) where const1 is the constant that has unit of (micro)meters per Joule and is currently implied rather than stated explicitly.
Best,
Jeff
