In general, 4% of Power (i.e. Power/25) = damage output. You can see this from hovering over tooltip of Power when you press C to bring up your Character Sheet stats.
But this is just an approximation because different Powers have different Power Coefficients. Not all Powers scale linearly with Power (especially Dailies) nor have the same Power Coefficient. Thus, weapon damage is far more reliable and much "cheaper" upgrade than Power where available.

how weird... no guides mention this.
So how can I gauge this? say for example weapon has less power, but more damage. How does damage translate to power?

Probably thought it was too obvious. I myself am making a guide, and I assumed it was obvious once you start leveling.
No offence
