Cooking Converter: Complete Guide with Formulas and Real-World Applications
What is Cooking Conversion?
Cooking conversion is the process of changing a measurement from one unit of cooking measurement to another. This is essential in many fields including culinary arts, baking, professional cooking, and home cooking. Different regions use different systems: North America typically uses imperial units (cups, tablespoons, ounces), while Europe and many other countries use metric units (grams, milliliters).
The conversion is based on standardized relationships between units. For example, 1 cup equals 240 milliliters, and 1 tablespoon equals 14.8 milliliters according to the US standard. These conversions are especially important in baking where precise measurements are critical.
Cooking Conversion Formulas
The general formula for cooking conversion is:
Converted Value = (Input Value × Target Factor) / Source Factor
Specific formulas for common cooking conversions:
- Cups to Milliliters: ml = cups × 240 (US standard)
- Tablespoons to Teaspoons: tsp = tbsp × 3
- Ounces to Grams: g = oz × 28.3495
- Cups to Fluid Ounces: fl oz = cups × 8
- Pounds to Grams: g = lb × 453.592
Important Note:
When converting between weight and volume measurements (grams to cups), remember that different ingredients have different densities. For example, 1 cup of flour weighs less than 1 cup of sugar. This converter assumes standard conversions based on water density for liquid measurements.
How to Convert Cooking Measurements
To convert between cooking units:
- Identify the units: Determine the original unit (e.g., cups) and the target unit (e.g., milliliters)
- Choose the correct formula: Select the appropriate formula for the specific unit conversion
- Apply the formula: Multiply or divide by the appropriate conversion factor
- Calculate: Perform the arithmetic to get the converted measurement value
Our calculator automates this process, providing accurate conversions instantly.

Cooking Conversion Tips
Here are some helpful tips for cooking conversions:
- 1 US cup equals 240 milliliters (236.588 mL according to US federal standard)
- 1 tablespoon equals 3 teaspoons
- 1 US tablespoon equals approximately 14.8 milliliters
- 1 cup equals 8 fluid ounces
- 1 pound equals 453.6 grams
- 1 gallon equals 3.78541 liters
- Kitchen scales provide more accurate measurements than volume measurements
- Different ingredients have different weights per cup (flour vs sugar)
- A pinch is approximately 1/8 teaspoon

Common Ingredient Density Table
For accurate weight/volume conversions, it's important to know the density of different ingredients:
| Ingredient | Weight per Cup (g) | Weight per Cup (oz) | Notes |
|---|---|---|---|
| All-purpose Flour | 120-125 g | 4.2-4.4 oz | Lightly spooned and leveled |
| Granulated Sugar | 200 g | 7 oz | Standard measurement |
| Brown Sugar (packed) | 220 g | 7.7 oz | Firmly packed |
| Butter | 227 g | 8 oz | 1 stick = ½ cup |
| Milk | 245 g | 8.6 oz | Approximately 1 g/ml |
| Water | 240 g | 8.5 oz | Exactly 1 g/ml |
FAQs
What is the difference between liquid and dry measuring cups?
Liquid measuring cups are clear with a spout and marked with measurements from the bottom up. Dry measuring cups are solid and designed to be filled and leveled off. While both measure the same volume, liquid cups are better for liquids as they reduce spills, and dry cups are more accurate for powders that need leveling.
How many teaspoons are in a tablespoon?
There are exactly 3 teaspoons in 1 tablespoon. This conversion is consistent across different measurement systems.
How do I convert cups to grams?
Converting cups to grams depends on the density of the ingredient being measured. For water, 1 cup = 240 ml = 240 grams, but for flour, 1 cup = approximately 120-125 grams. This converter uses standard conversions for liquid measurements.
Why is my cake dense when I measure flour incorrectly?
Incorrect flour measurement is a common baking mistake. Scooping flour directly with a measuring cup can pack the flour and add 20-30% more than intended. The correct method is to spoon the flour into the cup and level it off with a knife, or better yet, use a kitchen scale.
What is the difference between fluid ounces and weight ounces?
Fluid ounces (fl oz) measure volume, while weight ounces (oz) measure mass. The conversion between the two depends on the density of the substance. For water, 1 fl oz = 1 oz by weight, but for oils, 1 fl oz ≈ 0.9 oz by weight, and for honey, 1 fl oz ≈ 1.5 oz by weight.
