Kind of interesting that in the US you will hear 1g per lb of bodyweight. Go to Canada, the UK, or pretty much anywhere they use Metric they will say 1g per kilogram.
A kg is about 2.2 lbs. So that would basically be .5g per lb.
Everyones body is going to have its own chemistry so it will vary from person to person.
As long as you are at minimum the .5g/lb you are at a good point but you will need to adjust higher until you hit your sweet spot.
This is also something that will be a slightly dynamic number depending on your workout cycle.
Make sure you drink lots of water especially the higher protein you go. Your kidneys will thank you.
Also make sure you get your fats in as well. Your joints will appreciate it.
