Square cake tin to round cake tin conversions

A fellow blogger The Ordinary Cook recently asked about square to round cake tin conversations so I thought it would be nice to share the information with everybody.

Square cake tin to round cake tin conversions

As a general rule of thumb, a square tin holds approximately 25% more than a round tin of the same size; therefore reduce the round cake tin size between 2cm and 2.5cm (±1 inch) to arrive at the equivalent size of a square tin.

Approximate conversions

Round Tin                               Square Tin

15cm or 150mm (6 inch)           13cm or 130mm (5 inch)

18cm or 180mm (7 inch)           12.5cm or 125mm (5 inch)

20cm or 200mm (8 inch)           18cm or 180mm (7 inch)

23cm or 230mm (9 inch)           20cm or 200mm (8 inch)

25cm or 250mm (11 inch)         23cm or 230mm (9 inch)

28cm or 280mm (11 inch)         25.5cm or 255mm (10 inch)

30cm or 300mm (12 inch)         28cm or 280mm (11 inch)

Also, If you are using a square tin for a round tin recipe, keep the oven temperature the same, and turn the cake halfway through baking, as the corners tend to cook faster than the middle.

The older recipe books give certain ingredient weights in grams and a some of us today don’t have scales to measure out grams.  This table will eliminate uncertainties for you.

Microwave oven conversions

Microwave cooking and heating instructions are usually given based on a 700W to a 750W microwave oven. They don’t however provide a guide for a higher or lower wattage microwave oven.

Hope this helps.

Cake tin size conversions

How often have we searched for a tape measure that shows inches and centimetres to correctly gauge the size of an inherited cake tin which we know is 8 inches but need to know how many centimetres it is.  Hopefully this guide will make things a bit easier.

Quite often recipe and cookery books only provide measuring conversions relevant to the recipes in that specific book.

This is a comprehensive list for spoon and cup conversions to millilitres.

Temperature conversions

Today’s little tit-bit is temperature conversions.  This is especially helpful when using “foreign” recipe books or those inherited from Granny that don’t always show temperatures the way we are accustomed to seeing them.
