Deep Fry Oil Calculator

How it is calculated

The pot is treated as a straight cylinder. With inside diameter D and oil depth h, both in centimetres, the volume is V = π × (D ÷ 2)² × h in cubic centimetres; dividing by 1000 gives litres. The tool also shows US quarts, litres × 1.05669. Both inputs must be above zero. The tool also rejects a diameter above 100 cm or a depth above 60 cm, since no real pot is that large, and then shows no result. It does not compare the depth with your pot's height, so leave clear room below the rim yourself. Measure the inside diameter at the oil surface: a pot with sloping sides holds less than the cylinder suggests, so the result is an upper estimate for such shapes.

Common mistakes

• Entering the radius instead of the diameter. Half the width gives a quarter of the oil, so measure across the pot, not from the centre.
• Using the outside diameter. The wall thickness and the handles are not oil space, so measure the inside.
• Filling to the depth the pot could hold. Frying oil bubbles up once food goes in, so choose a depth well below the rim, not the full pot height.
• Mixing units, such as a diameter in inches and a depth in centimetres. Both fields are centimetres; a diameter over 100 or a depth over 60 is refused as an impossible size.
• Assuming straight sides on a wok or a pot that narrows towards the bottom. The tool uses a cylinder, so it overestimates the oil for those shapes.
