Sibley - US birds. Is this still imperial measurements only? (1 Viewer)

Slightly off-topic, but does anyone know if the Sibley app (and book, if there is a new edition) is still imperial only?

Hoped they would, by now, have a setting to change to metric for users in the rest of the world. Can't get my head around 3 3/8 oz, etc.

I thought scientific subjects all used metric, even in America. Is that not so?
The second edition Sibley (2014) is imperial for lengths and wingspan but gives the metric equivalent for weights.
Thanks Mono. (I've been to Mono Lake).

Thanks also jmepler. Luckily I'm on Android so I may now take the plunge when I next visit America.
