17 grams of sugar in 1 liter yields 1% alcohol upon complete fermentation.
Everything that follows is based on this:

1 gallon, 12% alc:
exact = 1.8 lbs sugar

1 gallon, 14% alc (Lalvin D47, 71B yeast):
exact/bone dry = 2.2 lbs per gallon = 2.75 lbs of honey
semi dry = 2.25 lbs per gallon = 2.8 lbs of honey
semi-sweet = 2.3 - 2.5 lbs per gallon = 3 lbs honey
sweet = 2.75 lbs sugar = 3 lbs honey + 0.25 lbs sugar

1 gallon, 16% alc (Lalvin RC-212 yeast)
exact/dry  = 2.5 lbs per gallon = 3.2 lbs honey (3 lbs honey + 2.25 oz sugar)
semi-sweet = 2.75 lbs sugar = 3 lbs honey + 4 to 5 oz sugar

1 gallon, 18% alc (Lalvin EC & K1V yeast):
bone dry  = 2.7 lbs per gallon = 3.4 lbs honey (3 lbs honey + 0.25 lb sugar)
exact/dry = 2.7 lbs per gallon = 3.4 lbs honey (3 lbs honey + 0.3 lb sugar)
semi-sweet  = 2.8 lbs per gallon = 3.5 lbs honey (3 lbs honey + 0.5 lb sugar)

3 gallons, total sugar, 12% alc:
exact/dry: 5.4 lbs sugar = 6.75 lbs honey (or 6 lbs honey + 0.6 lb sugar)

3 gallons, total sugar, 14% alc:
dry: 6.6 lbs sugar = 8.4 lbs honey (or 6 lbs honey + 2 lbs sugar or 7 lbs honey + 1 lb sugar)
semi-sweet: 7 lbs sugar = 8.75 lbs honey (or 7 lbs honey + 1.25 lbs sugar or 8 lbs honey + 0.8 lb sugar)

3 gallons, total sugar, 16% alc:
dry: 7.35 lbs sugar = 9 lbs honey (or 6 lbs honey + 2.5 lbs sugar or 7 lbs honey + 1.75 lbs sugar)

3 gallons, total sugar, 18% alc: 
bone dry: 7.8 lbs sugar or 9.75 lbs honey (or 6 lbs honey + 3 lbs sugar or 7 lbs honey + 2.25 lbs sugar)
exact/semi-dry: 8 lbs sugar or 10 lbs honey (or 6 lbs honey + 3.5 lbs sugar or 7 lbs honey + 2.5 lbs sugar)
semi-sweet: 8.5 lbs sugar or 10.5 lbs honey (or 6 lbs honey + 4 lbs sugar or 7 lbs honey + 3 lbs sugar)
sweet: 8.75 lbs sugar or 11 lbs honey (or 7 lbs honey + 3.5 lbs sugar or 8 lbs honey + 2.5 lbs sugar)

5 gallons, total sugar, 18% alc:
bone dry: 13.25 lbs sugar or 17 lbs honey (or 12 lbs honey + 3.5 lbs sugar or 10 lbs honey + 5 lbs sugar)
semi-dry: 13.5 lbs sugar or 17 lbs honey (or 12 lbs honey + 3.75 lbs sugar or 10 lbs honey + 5.5 lbs sugar)
semi-sweet: 13.75 lb sugar or 17.25 lb honey (or 12 lb honey + 4.5 lb sugar or 10 lb honey + 6 lb sugar)
sweet: 14.25 lbs sugar or 18 lbs honey (or 12 lbs honey + 5 lbs sugar or 10 lb honey + 6.5 lb sugar)
