Hop flowers versus pellets.

[Alex.mc]

Are they considered equivalent by weight? Or should you use more whole hops for the same effect? Or the same amount but for longer?

[Drunkula]

Pellets give out 10% more hop type things according to the internets.

Brewers Friend do an IBU calculator where you specify using leaf or pellet.
