Use 1 cup sugar to 4 cups water. This is what I have read every time I look it up on line.
Ditto on the above - 1 cup (white) sugar to 4 cups water. I don't even boil the water - just stir til the sugar dissolves. I keep any extra in the fridge and let sit a bit before I put it out to take the chill out of it - Although nowadays the hummers would probably appreciate a bit of a chill.
There are two suggested ratios given: 1 part sugar to 3 parts water, or 1 part sugar to 4 parts water. Since you're using 2 liters (or "Litres") of water, then you would either add: 1/2 (.5) liter of sugar (for the 1:4 ratio) *or* 2/3rds (.666) liter of sugar (for the 1:3 ratio.)
Apparently no one else realized you were on Metric, but the math should have translated just the same.
That is not a correct calculation, it should be 400 ml of sugar and 1600 ml water, or 500 ml sugar and 1500 ml water.
