Does light or fat-free sour cream weigh the same as regular?

The difference is small enough to ignore for most recipes. This converter uses 240 g/cup, which works well across regular, light, and fat-free sour cream.

Is 1 cup of sour cream the same as 240 ml?

Yes. 1 US cup equals 240 ml as the culinary standard, and since sour cream density is close to 1 g/ml, the gram weight comes out to roughly the same number as the milliliter volume.

Why do some recipe sites list a different gram figure for sour cream?

Sour cream density varies slightly by brand and fat content, so some sources round to 230 g or 245 g per cup. 240 g/cup is the standard baking-reference figure used here and matches the companion grams-to-cups converter.
