About

Recipe measurements vary across regions. US recipes default to volumetric units (cups, tablespoons), while European and professional kitchens rely on metric weight (g, kg). A miscalculated flour conversion - 1 cup of all-purpose flour equals approximately 125 g, not 150 - can ruin baked goods by altering hydration ratios. This converter handles volume, weight, and temperature units used in cooking. It parses fractional inputs (1½, ¾) natively, since most printed recipes use fractions rather than decimals.

Temperature conversions include Gas Mark, a scale still referenced in British cookbooks. Note: volume-to-volume and weight-to-weight conversions are exact. Cross-domain conversion (volume to weight) depends on ingredient density and is not covered here. For baking precision, weigh ingredients directly.

Formulas

Volume conversions use a base-unit normalization strategy. Every unit is defined by its factor relative to 1 mL. To convert from unit A to unit B:

result = value × factor_Afactor_B

Where factor_A is the number of milliliters per unit A, and factor_B is the number of milliliters per unit B. Weight conversions follow the same pattern with 1 g as the base.

Temperature uses independent linear formulas:

T_°C = 59 × (T_°F − 32)

T_°F = T_°C × 95 + 32

Gas Mark conversion uses a lookup table for standard marks (1 - 10) with interpolation: Gas Mark 1 = 275 °F (135 °C), incrementing by 25 °F per mark. Fraction parsing converts mixed numbers: input 1 3/4 is parsed as 1 + 34 = 1.75.

Frequently Asked Questions

A cup is a volume measurement (236.588 mL), not a weight measurement. Different ingredients have different densities. All-purpose flour is approximately 125 g per cup due to air pockets, while granulated sugar packs more densely at approximately 200 g per cup. This converter handles volume-to-volume and weight-to-weight conversions. Cross-domain conversion requires ingredient-specific density data.

A US tablespoon equals 14.787 mL (3 US teaspoons), while a metric tablespoon used in Australia and New Zealand equals 20 mL (4 metric teaspoons). This 35% difference is significant in baking. When following an Australian recipe, select Metric Tablespoon in this converter.

Gas Mark is a discrete scale, not a continuous one. Standard marks run from 1 (275 °F / 135 °C) to 10 (500 °F / 260 °C), incrementing by 25 °F per mark. Fractional marks (¼, ½) exist for lower temperatures. The converter interpolates linearly between standard marks. Actual gas oven calibration varies by manufacturer.

Yes. The input parser recognizes pure fractions (2/3), mixed numbers (1 1/2), and decimals (1.5). Unicode fraction characters (½, ¼, ¾) are not parsed; use the slash notation instead. The result displays both the decimal value and the nearest common cooking fraction where applicable.

A US fluid ounce is 29.574 mL, derived from the US gallon (3785.41 mL ÷ 128). An Imperial fluid ounce is 28.413 mL, derived from the Imperial gallon (4546.09 mL ÷ 160). The 4% difference compounds in larger volumes. An Imperial pint is 568 mL versus 473 mL for US. Always verify which system a recipe uses.

These informal units have standardized approximations in US cooking: a pinch is 1/16 teaspoon (0.308 mL), a dash is 1/8 teaspoon (0.616 mL), and a smidgen is 1/32 teaspoon (0.154 mL). Specialty measuring spoon sets include these sizes. For critical recipes requiring sub-teaspoon precision, use a milligram scale instead.
