Mizen automatically converts ingredient measurements between metric and imperial unit systems, making recipes accessible to cooks worldwide.

How It Works

The unit converter analyzes each ingredient’s units and converts them to your preferred system:
  • Original - Keep measurements as written in the recipe
  • Metric - Convert to grams, kilograms, milliliters, and liters
  • Imperial - Convert to cups, tablespoons, teaspoons, ounces, and pounds

Conversion Logic

Mizen uses precise conversion ratios for accurate measurements: Volume Conversions (base unit: milliliters)
  • 1 cup = 240 mL
  • 1 tablespoon (Tbsp) = 15 mL
  • 1 teaspoon (tsp) = 5 mL
  • 1 fluid ounce = 30 mL
  • 1 liter = 1000 mL
Weight Conversions (base unit: grams)
  • 1 pound (lb) = 454 g
  • 1 ounce (oz) = 28 g
  • 1 kilogram (kg) = 1000 g
Mizen intelligently handles the ambiguous “oz” unit by analyzing the ingredient name. Liquid ingredients (water, milk, oil) use fluid ounces, while solid ingredients use weight ounces.

Conversion Examples

Metric to Imperial

Original: 250 mL water
Imperial: 1 cup water
Original: 500 g flour
Imperial: 1 lb flour
Original: 15 mL vanilla extract
Imperial: 1 Tbsp vanilla extract

Imperial to Metric

Original: 2 cups sugar
Imperial: 480 mL sugar
Original: 1½ lb chicken
Metric: 681 g chicken
Original: ¾ cup butter
Metric: 180 mL butter

Range Conversions

Mizen preserves ranges and converts both values: Original: 2-3 cups broth
Metric: 480-720 mL broth
Original: 1 to 2 tsp salt
Metric: 5 to 10 mL salt

Smart Unit Selection

The converter automatically chooses appropriate units based on quantity:

Metric System

  • Small volumes (< 1000 mL) → milliliters
  • Large volumes (≥ 1000 mL) → liters
  • Small weights (< 1000 g) → grams
  • Large weights (≥ 1000 g) → kilograms

Imperial System

  • Very small volumes (< 15 mL) → teaspoons
  • Small volumes (15-240 mL) → tablespoons
  • Medium volumes (≥ 240 mL) → cups
  • Small weights (< 454 g) → ounces
  • Large weights (≥ 454 g) → pounds

Non-Convertible Units

Some measurements can’t be converted because they’re qualitative or countable:
  • Countable items: 2 cloves garlic, 1 onion, 3 eggs
  • Qualitative measures: pinch of salt, handful of herbs, to taste
  • Package sizes: 1 can tomatoes, 1 box pasta
  • Descriptive sizes: 1 large carrot, 2 medium potatoes
These ingredients remain unchanged regardless of the unit system selected.

Fraction Formatting

Converted amounts are displayed using Unicode fraction symbols for readability:
  • ½ (0.5)
  • ⅓ (0.333)
  • ¼ (0.25)
  • ¾ (0.75)
  • ⅛ (0.125)
  • ⅔ (0.667)
Example: 0.75 cups converts to ¾ cup, not “0.75 cup”
Unit conversion works seamlessly with recipe scaling. When you adjust servings, Mizen first scales the ingredients, then converts them to your preferred unit system.

Limitations

Volume vs. Weight

Mizen converts units but doesn’t convert between volume and weight. For example:
  • 1 cup flour ≠ a specific number of grams (density varies)
  • The converter maintains the measurement type (volume or weight)

Precision

Conversions are rounded to practical cooking measurements:
  • Very small amounts (< 0.125) display as ”< ⅛”
  • Decimal values round to the nearest common fraction
  • Amounts within 2% of whole numbers round to whole numbers

Context-Dependent “Oz”

The “oz” abbreviation can mean fluid ounces (volume) or ounces (weight). Mizen analyzes the ingredient name to determine which:
  • Liquids: water, milk, oil, juice → fluid ounces (30 mL)
  • Solids: flour, sugar, cheese → weight ounces (28 g)
For ambiguous cases, review the conversion to ensure accuracy.
