Equal Sweetner against sugar - Comparison with Wrong Amounts?

[amsdcj]

This ClubEqual Sweetner says that the sweetner has 8kJ (2 Cal)
per serve of 1 level teaspoon (0.5g) than it compares it to
sugar, that says it has 68kJ (16 Cal) per serve of 1 level
teaspoon. But when I look on the sugar packet, it says it has
68kJ (16 Cal) per serve of 1 level teaspoon (4g).

Is the sweetner still 8 times less fatning than sugar. I dont
understand, they're comparing at wrong amounts (saying that 1
level teaspoon is 0.5 g for ClubEqual Sweetner, and 4g for
sugar_. Than when you look per 100g, the sweetner isn't even 2
times less fatning than sugar.

statistics, and how much time is Splenda and Equal less
