184 grams is a touch high for “a cup of flour”, but I’m not gonna check your math, and the comic probably wanted to use “close enough” round-ish numbers. The weight of a cup of flour is usually somewhere between 120g and 145g, going by the conversions used by major baking recipe publishers like King Arthur, Cooks Illustrated, Washington Post, New York Times, etc.

I fear their apartment is at -50°C and this is a cry for help.

At least I am relieved to know that even acclaimed authors native to the cup-measurement system don’t know what “a cup of flour is”.

I’ll be off baking my pannenkoek with 150g of flour then.

I figured it out. Typed the ln2 into my text and then forgot it in the calculator.
Great, I’ma redo alll my numbers then rq

Mass, not weight! Only because we’re being technical already.

  Grams are a measure of mass or weight. I assume we’re talking about measuring this flour here on planet earth, within the effects of its gravitational field lol

    At what elevation and where in Earth? 🤔 Again, only being this technical because that’s the tone. Not being pedantic.

    The variance involved in converting cups of flour to grams is much greater than any gravitational variances caused by elevation or location. So that’s sort of irrelevant here.

    This is a great second argument for using weight not volume for measurements.
    Measuring mass is of course not viable, but measuring weight in a consistent location means all the ratios end up correct. While ratios between volume and weight measured substances change (and flour probably compacts differently).
    That is why one should always use a scale to measure their fluids, and why metric is superior where 375ml of water or milk are 375g (convert the recipe ahead of time at a reference location), making this trivially easy.
    
    If you wish to then correct the total mass of your dish, you can simply compare the weight and volume of water to work out the mass to weight ratio and correct accordingly.
