Because sugar cubes don’t neatly add up to a full tablespoon of sugar without going either under or over, I’d recommend being careful when using sugar cubes to replace tablespoons. Depending on what it is you’re trying to sweeten, you may over (or under) use the sugar cubes. Try measuring your sugars for a tablespooon the traditional way instead.

Because of these wild fluctuations in measurement, I recommend you don’t try to measure whole cups of sugar using cubes. Instead, I recommend you use free-flowing granulated sugar as this will save you from the dilemma of having more or less sugar than you actually need.
