To convert ounces of graham cracker crumbs into cups, multiply by 0.19964453: one ounce comes to 0.19964453 cups. Every ingredient has its own figure here, because the units are measuring different things and only the density links them.
Water is the yardstick: 1 mL of it weighs 1 g. Graham cracker crumbs comes in at 0.6002 g per mL, or 60.02% of water, which is why a cup of it is 142 g rather than 236.6 g. Volume and weight only line up for water, and only in metric.
A cup of graham cracker crumbs is 142 g when it is measured the standard way, but how it gets into the cup changes the answer: between about 127.8 g and 170.4 g covers the range from lightly spooned to firmly packed. That 20% spread is larger than most of the adjustments recipes fuss over, and it disappears entirely the moment the ingredient is weighed instead.
One cup of graham cracker crumbs is 5.009 oz. US kitchen scales usually step in eighths of an ounce, which is 3.54 g — around 2.5% of a cup of this ingredient, so the scale is precise enough for a full cup and coarse for a spoonful. That is why recipes mix the two systems: ounces for the bulk, spoons for the small amounts.
What the number depends on: Finely crushed. A 9-inch crumb crust takes about a cup and a half of them.
The formula
ounces- The amount of graham cracker crumbs you are converting, in ounces
0.199644529049- Cups per ounce for graham cracker crumbs, from its density of 0.6002 g/mL
cups- The equivalent quantity in cups
How it works, step by step
- Enter the quantity in ounces.
- It is multiplied by 0.199644529049, the cups-per-ounce figure for graham cracker crumbs.
- The result appears in cups, with a second reading in tbsp beneath it.
- Use the measure table if you want a standard recipe quantity rather than a number you type in.
Worked examples
2 oz of graham cracker crumbs in cups
A recipe calling for 2 oz of graham cracker crumbs needs 0.399289 cups on the scale. The arithmetic is 2 × 0.19964453 = 0.39928906, and halving the recipe halves the weight to 0.199645 cups.
4 oz of graham cracker crumbs in cups

Frequently asked questions
How many cups are in 1 oz of graham cracker crumbs?
One ounce of graham cracker crumbs is 0.19964453 cups. Half that quantity is 0.0998223 cups and double it is 0.399289 cups, so the figure scales straight up and down — there is no offset in this conversion, only the factor.
Why is a cup of graham cracker crumbs not 236 g like water?
Because weight per cup depends on what is in the cup. Graham cracker crumbs has a density of 0.6002 g per mL where water has 1.00, so a cup of it weighs 142 g rather than 236.6 g. That is a difference of 94.6 g per cup, and it is the reason a single volume-to-weight factor cannot be applied to every ingredient.
Does how I measure it change the weight?
Yes, and by more than most people expect. Handling changes the weight of a cup of graham cracker crumbs by roughly 20% — about 14.2 g either side of 142 g — because finely crushed. Weighing removes the question entirely.
Is a fluid ounce of graham cracker crumbs the same as an ounce?
No. A fluid ounce is a volume — one eighth of a US cup, 29.57 mL — and an ounce is a weight. One fluid ounce of graham cracker crumbs weighs 0.6261 oz, so the two readings differ by 37.4%. They coincide only for something with the density of water, and then only roughly.
Is this a US cup or a metric cup?
US customary: 236.59 mL, which is the cup every US recipe means. A metric cup is 250 mL, so the same cup of graham cracker crumbs would weigh 150.05 g instead of 142 g — 8.05 g more, or 5.67%. Australian and some European recipes use the metric cup, and the difference is large enough to matter in baking.
Do I need a scale for this, or will measuring cups do?
A scale, if the result matters. Volume measuring carries a spread of about 20% for graham cracker crumbs — roughly 28.4 g on a 142 g cup — while a domestic scale is accurate to a gram or two. For anything where the ratio of ingredients drives the outcome, bread and pastry above all, weigh it.
How much does 2 cup of graham cracker crumbs weigh?
2 cup of graham cracker crumbs comes to 284 g, or 10.018 ounces. This page runs that calculation in reverse — enter a weight and it returns the volume — and the cups-to-ounces page does it in the direction the question is usually asked.
