Brine Calculator Work out the salt for a brine at any strength from the water weight. Shows the salt to weigh, the total brine weight and the refrigerator rule for brining. Cake Pan Converter Convert a round, square or rectangular cake tin to another size. Get the area ratio that multiplies every ingredient, and how the baking time changes. Candy Temperature Chart Sugar stage temperatures from thread to caramel in °C and °F, shifted for your altitude by the boiling point of water there. Figures from Wikipedia.

Weights are more reliable than cups; the tools show both where it helps.
