This is my first time making an underquilt and I was curious of the approximate weight of 850fp down needed for a 3/4 length UQ rated to 20 degrees Fahrenheit? Any suggestions or ideas are much appreciated.

Take the length, width, and height of your UQ and plug them into the following formula:
(L*W*H)/850
This will give you a rough estimate of how many ounces of down you will need.
Most people tend to add an extra 20% of down to their quilt to prevent down drifting and give a slight temp boost as well.
For a 20°F quilt your looking at around a 2 inch chamber height.
My advice is figure how tall you want your baffles to be, then cut them a half inch shorter and add an additional 10%-20% down over what your initial height would have been.
But I'm a belt and suspenders kind of guy, I'm working on fixing that though.

Ultimately it depends on the dimensions of the quilt, but hammockgear lists 8oz of fill for the 20 degree phoenix underquilt

Thanks for the info Cataverie!
Thanks Brucky. I did look at that sight before I posted, but I was looking for something a little more plug and play. I think they slightly overfill.
