Yes, that's what I do. (I HATE those priming calculators because they try to guestimate residual co2 as well as prime to "style" so many people get overcarbed or undercarbed beer!)
I use .75 ounces of corn sugar (dextrose) per gallon of beer for lower carbed styles, and 1 ounce of corn sugar per gallon of beer for more highly carbed styles. It works perfectly for me, and I never have had undercarbed or overcarbed beer, in all these years.
