Sugar Priming Question

[love2brew]

I made a batch with too match water, was suppoose to be 5 gallons but I used 22.5 litres. How much priming sugar should I use? I noticed my beers are not as carbonated as I like. I used 3/4 cups dextrose previously in a 22.5 litre batch

Use the calculator link below and add priming sugar by weight not volume. Volume can change just by tapping the cup and settling the sugar. I also switched to regular table sugar for priming about 10 batches ago and now my carbonation is consistent. I switchd to cane beacause I understand it absorbs less water than corn so the weight is more accurate.
