Ingredient Calculator $9.99 one-time

For home bakers who are tired of inconsistent results

Baking by weight

A cup is a volume, and flour is compressible, so the same cup can vary by a wide margin depending on how you filled it. This is the fix: what to weigh, what the numbers actually are, and the one liquid measurement almost every chart gets deliberately wrong.

What you get

Why your cup measurements keep betraying you

41 pages. PDF, sized for a phone. No fluff chapters, no padded intro, no upsell at the end.

  • Every density from one named source. Twenty-five ingredients taken from the King Arthur Baking chart and nowhere else, so the figures cannot quietly disagree with each other.

  • The scooping problem, measured. Why the same cup of flour ranges so widely, which ingredients vary most, and how to scoop consistently when you have no scale.

  • The water discrepancy explained. The one measurement where the standard chart and physics disagree, why both answers are defensible, and which to use when.

  • Derived rows flagged as derived. Where the source lists a half cup or a tablespoon, the per-cup figure is marked and the rounding error is shown, so you know which numbers to trust least.

  • A reference table for the ingredients people actually convert, not an exhaustive list you will never read on a phone.

A cup of water does not weigh what the chart says

This is one of the 41 pages, in full. If it is useful on its own, the rest will be too.

The water problem, and why 227 is not wrong

King Arthur lists one cup of water at 227 grams. A US cup is 236.6 millilitres and water is within a fraction of a percent of one gram per millilitre, so a cup of water weighs about 236 grams, not 227. The 227 figure is the baking shorthand that treats eight fluid ounces as eight ounces of weight. It is a convention, not a density.

Both numbers are defensible and the gap is 4.13%. In a bread dough with 500 grams of flour, one cup of water is either 45.4 percent hydration or 47.2 percent. Almost two points is something you feel in your hands. Use 236 where the ratio is tight, use the chart figure where the recipe has slack, and never mix the two inside one recipe.

Why trust this

Where it comes from

  • Every gram figure comes from the King Arthur Baking ingredient weight chart, retrieved and verified twice. No number was taken from this site's own converter.
  • Where the source disagrees with physics, or with itself, the guide says so and shows both figures rather than quietly picking one.

I build the converter this site runs on. The densities in this guide are the ones I would use myself.

Questions

Before you buy

What exactly do I get, and how?
A PDF, in A4 and US Letter. The download link appears on the confirmation screen the moment payment clears. You do not wait for an email, and you do not need one to arrive.
Do I need an account?
No. There is no account, no login and no password. You pay, the file downloads, and that is the whole relationship unless you choose to email me.
What is the refund policy?
Thirty days, no questions asked. Email [email protected] and say refund. No form, no reason required, no attempt to talk you out of it. You keep the PDF.
Will it open on my phone?
Yes. It is a standard PDF, so it opens in Files on iPhone, in Drive or any reader on Android, and in every desktop browser. It prints cleanly if you prefer paper.
Is this just the free converter in a PDF?
No. The figures come from a published weight chart and are cited in the guide, and where that chart disagrees with physics the guide shows both numbers and explains the difference.
Who is this not for?
If you want tactics that promise growth, skip it. This is a ledger. It is useful if you are deciding whether to build a portfolio like mine, and most useful if it talks you out of it.
