Grape tomatoes

Anyone know how many carbs are in grape tomatoes? I’m assuming that since they are so much sweeter than regular roma or beef steak tomatoes, that they have more, but haven’t been able to find any info on the internet or in books. I did find that cherry tomatoes are 1 carb each. I would like an estimate for about 1 cup of grape tomatoes (usually cut in half).

Thanks

I’ve found a link to a site that SHOULD contain such information, but if so, does not appear to have put it in the more obvious locations in their list:

You may need to check if grape tomatoes have any alternate names to look under.
