Why does ingredient matter?

A cup of flour weighs much less than a cup of sugar. To convert volume (cups) to weight (grams) accurately, we must know the density of the specific ingredient.

How many grams is a cup of flour?

It depends on how you pack it, but the standard accepted weight for All-Purpose Flour is 120 grams per cup. Cake flour is lighter (114g).

What is a 'packed' cup?

Brown sugar is often measured 'packed', meaning you press it down into the cup. This fits more sugar into the same volume, making it heavier (220g) than loose white sugar (200g).

Can I convert liquids?

Yes. For water-based liquids (milk, vinegar, juice), 1 ml equals 1 gram. Oils and honey have different densities, which our tool accounts for.

Is this accurate for baking?

Yes. We use standard culinary density charts. However, for the absolute best results in baking, we always recommend using a digital scale and measuring by weight (grams) directly.

The "Cup" Problem

If you've ever baked a cake that turned out dry and dense, the culprit was likely your measuring cup.

Depending on how you scoop it, a "cup" of flour can weigh anywhere from 100g to 150g. That's a 50% difference! Professional bakers use weight (grams) because it is precise. A gram is always a gram.

Our Cooking Units Converter bridges the gap. It uses precise density data to tell you exactly how much that "1 cup of butter" weighs, so you can use your scale and get perfect results every time.

Common Kitchen Conversions

🧈 Butter

1 stick = 1/2 cup = 113g = 4 oz
1 tbsp = 14g

🍚 Flour (All-Purpose)

1 cup = 120g
1 tbsp = 8g

🍬 Sugar (White)

1 cup = 200g
1 tbsp = 12.5g

💧 Liquids (Water)

1 cup = 237ml = 237g
1 tbsp = 15ml
1 tsp = 5ml

Volume vs. Weight

Volume measures how much space something takes up (cups, spoons, liters).
Weight measures how heavy something is (grams, ounces, pounds).

You can convert between them ONLY if you know the density. That's why this tool asks you to select an ingredient. Converting "cups" to "grams" without knowing if it's lead or feathers is impossible.

Frequently Asked Questions

What is a "heaping" tablespoon? ▼

A heaping spoon is piled as high as it can go. It's inaccurate. This calculator assumes "level" spoons, where you scrape the top flat.

US Cup vs. Metric Cup? ▼

Great question. A US Cup is ~237ml. A Metric Cup (used in Australia, NZ, Canada) is 250ml. This tool currently uses the standard US Cup (237ml) as it is the most common in online recipes.
