Length and fabric conversions
Inches to centimetres, metres to yards and millimetres to inches cover most fabric, yarn and pattern measurements. Because fabric is often sold by the metre but patterns are written in inches, a quick conversion prevents buying too little.
Weight and volume for materials
Wax, resin, clay and fibre are sold by weight but worked by volume. Convert grams to ounces, kilograms to pounds and millilitres to cups so a recipe scales correctly whatever unit it was written in.
Craft-specific sizes
Ring sizes, paper sizes and temperatures do not follow a simple formula. Dedicated converters map the standard scales used in the UK, US, EU and Japan so you can order materials or follow a pattern with confidence.
