Did this up last night with the cask strength 10 year old as that's what I had on hand. It's one of the few cocktails I've tried with this much green chartreuse where it didn't overwhelm the cocktail. Smoky, herbal, yet oddly refreshing.

For some reason this cocktail has an inconsistent recipe across the internet and it comes down to one ingredient - the Yellow Chartreuse. Here on this very website if you switch from oz to ml you get from 1/4 oz, in what I would call the American version to 1/3 oz (1 cl/10 ml) - either your website converter doesn't work or the recipe all of a sudden changed for the European market because it is easier to get the Chartreuse here :P

Then if you had over to the Washington Post where I first saw the recipe for this cocktail, the Yellow Chartreus here is 1/2 oz or double what Dan here has put: https://www.washingtonpost.com/recipes/laphroaig-project/15533/

Does anyone know what the original mix calls for???

This site does seem to use a 1/4 oz ~> 1 cL conversion. I don't know why, but I'm also not sure how common metric jiggers with sub-10mL markings are. The oXo angled measure seems to have one that may correspond to the 1/4 oz line. I have not tested to see what the cL->oz conversions do. I browse using oz measurements and the measurement units page appears more accurate if you need to convert a metric recipe.

I think the Internet Archive cache of the reference used here is definitive for the recipe, given the page was made by the bar, the early post date, and the fact the WaPo article mentions another adjustment (a more affordable scotch). This uses 1/4 oz.

1 cL is almost exactly 1/3 fluid ounce (0.33814). The easiest way to remember this is that 1 oz ~ 30 mL (29.5735 mL). 1 cL = 10 mL.

Erick Castro on today's episode of Bartender at Large (the one with Paul Clarke) talked about how the Yellow Chartreuse started at 1/2 oz but it was soon lowered to 1/4 oz which is why there are a few recipes out there with the larger amount. Erick also joked that it helps with the pour cost in 2024 opposed to when a lot of these bottles were more than half the price back and easy to get in 2009...
