I have given up on web pages for recipes. Videos are still mostly fine. Often a nice condensed version of the recipe will be in the comment section.

Nowadays a cup and a tablespoon are standard unities of volume. They are not any worse than milliliters. There are a few people that insist on ignoring the standards, but those also tend to not publish their recipes.

The issue is that for a lot of ingredients -- flour notably among them -- you can't measure accurately by volume. If you're looking for reproducibility, you have to measure by weight.

And once you start measuring some things by weight, you quickly realize that most things are easier to measure out by weight than volume (particularly sticky ingredients like honey), so you start wanting to measure everything that isn't a tiny amount by weight.

I convert all of the recipes I collect to gram measurements for this reason.

You cannot measure flour, sugar, salt, etc by volume. Cups of flour and *spoins of sugar/salt/cinnamon and even butter are used in (too) many recipes.
