Ceramic Measurement Conversions

Ceramic recipes, kiln specifications, and studio measurements exist in a mix of metric and imperial units depending on country of origin. A UK kiln spec gives volume in liters; a US recipe lists materials in pounds; a Japanese formula uses grams. This converter handles all four categories relevant to ceramics: length, weight, temperature, and volume.

Common Conversion Reference

From	To	Factor
1 inch	Millimeters	25.4 mm
1 pound	Grams	453.6 g
1000°F	Celsius	537.8°C
1 US gallon	Liters	3.785 L
Cone 6 (1222°C)	Fahrenheit	2232°F

Temperature and Ceramics

Temperature conversion is especially important when working with kilns from different countries or following recipes written for different markets. Note that Celsius is the standard in most ceramic literature worldwide, with the US being the main exception. Cone temperature equivalents are given in both scales in the Cone Temperature Calculator.

lightbulb Quick Tips

check_circle When following a recipe from a different country, check whether temperatures are in Celsius or Fahrenheit — it's the most common source of confusion.
check_circle 1 lb ≈ 453.6g. For quick mental math: 1 lb ≈ 450g is close enough for most glaze batches.
check_circle US potters: Cone 6 = 1222°C = 2232°F. Cone 10 = 1305°C = 2381°F. Good benchmarks to have memorized.

Frequently Asked Questions

How do I convert Celsius to Fahrenheit for kiln firing? expand_more

Use the formula: °F = (°C × 9/5) + 32. For example, Cone 6 at 1222°C = (1222 × 1.8) + 32 = 2232°F. This converter handles it automatically.

What is the difference between US fluid ounces and UK fluid ounces? expand_more

US fluid ounce = 29.57mL. UK (imperial) fluid ounce = 28.41mL. This calculator uses US fluid ounces. For UK measurements, the difference is small but note the distinction in precision glaze work.
