Cast Iron Calculators & Tools
Free, practical tools for cast-iron care and cooking — size a seasoning coat, schedule the oven, size a skillet to servings, estimate preheat time, plan a rust removal, and scale a recipe to your pan.
Seasoning Oil Amount Calculator
Work out how much oil a thin, even seasoning coat actually needs from your pan's diameter and wall height — in millilitres, teaspoons, and tablespoons.
Seasoning Oven Temp & Time Calculator
Get an oven temperature just below your oil's smoke point, plus a bake-and-cool schedule sized to however many coats you're building.
Skillet Size to Servings Calculator
Convert a skillet's diameter into a realistic serving count for a one-pan skillet meal, based on the pan's actual cooking-surface area.
Skillet Preheat Time Calculator
Estimate how many minutes it takes to bring a pan of a given weight up to searing temperature on gas, electric, or induction.
Rust Removal Planner
Turn a rust severity and method — vinegar soak, salt scrub, or electrolysis — into a soak time, scrub-pass count, and re-seasoning coats.
Recipe Scaling Calculator
Scale ingredient quantities by desired servings, or by the change in cooking-surface area when you move a recipe to a different skillet size.
