Does 1ml = 1g

[whyet]

I am thee worst at calculating stuff like this, I'd I wanted for example 15ml of Caesar dressing does this equal to 15g, I never thought this tbh until Google told me, is this true? Sorry if I'm silly

It’s true of water (or liquids that are basically water eg milk/juice). Might not be true of something thicker or oilier like salad dressing- however there’s probably not a significant difference in 15ml v 15g.

I would measure and weigh to find out

My scales have a ML and g and it's the same. Also a separate setting for Milk ML and there's about 1-2g in it. Not worth worrying over

100ml of olive oil weighs 92g. So if 15ml of olive oil was 135 kcal, then by weighing it you would actually have 16.5 ml and therefore 145 kcal. In the grand scheme of things, it makes not a huge difference. Especially when you think that whatever you measure it in will end up with some of your 16.5g coating it.

Rather surprisingly there's a website where you can look up food densities:

https://www.aqua-calc.com/page/density-table/substance/caesar-blank-dressing

and they say Caesar dressing has a density of 0.99g/ml. So 15ml would be 14.85g!

That's because most scales use the density of water (0.997 kg/litre, rounded up to 1kg/litre) to convert g to ml. Milk has a density of 1.03 kg/litre, so it will measure slightly differently.
