# Grams to Cups Converter

Convert grams to cups for flour, sugar, butter, rice, oats, milk, water, and honey. Accurate ingredient-specific conversion for baking and cooking recipes.

## What this calculates

Convert grams to US cups for common cooking and baking ingredients. Because different ingredients have different densities, a cup of flour weighs much less than a cup of honey. This tool uses standard baking references for accurate ingredient-specific conversions.

## Inputs

- **Weight** (grams) — min 0 — Enter the weight in grams.
- **Ingredient** — options: All-Purpose Flour, Granulated Sugar, Butter, White Rice (uncooked), Rolled Oats, Milk, Water, Honey — Select the ingredient for accurate conversion.

## Outputs

- **Cups** (cups) — Volume in US cups.
- **Tablespoons** (tbsp) — Volume in US tablespoons.
- **Ounces (weight)** (oz) — Weight in avoirdupois ounces.
- **Ingredient Note** — formatted as text — Density info for the selected ingredient.

## Details

Converting grams to cups requires knowing the density of each ingredient. Unlike volume-to-volume conversions, weight-to-volume depends entirely on what you are measuring. This tool uses widely accepted baking references for the most accurate results.

Grams per US Cup by Ingredient

Ingredient
Grams per Cup
Notes

All-Purpose Flour
125 g
Spooned and leveled, not scooped

Granulated Sugar
200 g
White granulated

Butter
227 g
Equals 2 standard sticks

White Rice (uncooked)
185 g
Long-grain

Rolled Oats
90 g
Old-fashioned, not instant

Milk
240 g
Whole milk

Water
240 g
Room temperature

Honey
340 g
Due to high density (~1.42 g/mL)

Conversion formulas

- Cups = Grams ÷ (grams per cup for ingredient)

- Tablespoons = Cups × 16

- Ounces (weight) = Grams ÷ 28.3495

Note that flour measurements can vary significantly depending on how the flour is measured. Scooping flour directly from the bag compacts it and can add 20-30% more flour than the spooned-and-leveled method. For best baking results, always use a kitchen scale.

## Frequently Asked Questions

**Q: Why do different ingredients have different grams per cup?**

A: Because ingredients have different densities. A cup measures volume, not weight. Light, airy ingredients like flour weigh less per cup (125 g) than dense liquids like honey (340 g). This is why professional bakers prefer weighing ingredients in grams.

**Q: How many cups is 250 grams of flour?**

A: 250 grams of all-purpose flour is approximately 2 cups, using the standard of 125 grams per cup (spooned and leveled). If you scoop flour directly, it may pack tighter, making this less accurate.

**Q: Is it better to measure by weight or volume?**

A: Weighing ingredients in grams is more accurate and consistent, especially for baking. Volume measurements like cups can vary depending on how the ingredient is scooped, packed, or leveled. A kitchen scale eliminates this variability.

**Q: How many grams are in a cup of butter?**

A: One US cup of butter weighs 227 grams, which is equivalent to 2 standard sticks of butter (each stick is 113.5 g or 4 oz). Half a cup of butter is one stick.
