Condensed milk in grams?!

[UtterlyButterly]

I'm new to baking so this is probably a stupid question!

I want to use condensed milk but the recipe says grams not ml.

Do I physically weigh it or can I convert it?

I think the two are interchangeable ( at least that's what my scales say)

I would weigh it, especially if you have the type of scales that you can put your mixing bowl on and zero the scales. Less messy too.

Interchangeable. Just found that out this year
