Work out deep fry oil quantity instantly with clear inputs, formula shown and shareable results.
Oil volume is the pot cross-section times the oil depth; frying oil weighs about 0.92 kg per litre, and a batch should not exceed roughly a quarter of the oil weight. Overloading the pot crashes the oil temperature and makes food greasy, and the headroom figure is a safety check because oil foams up sharply when wet food goes in.
Oil volume
litres = pi x (diameter / 2)^2 x oil depth / 1000
Batch limit
maximum batch grams = oil weight in kg x 250
