Cooking Unit Converter
🇦🇺 Australia version
An Australian tablespoon holds 20 mL, not the 15 mL or 14.8 mL found elsewhere, so a recipe swapped across the Tasman or the Pacific quietly changes. This converter uses the 20 mL tablespoon, a 250 mL cup and weights for 50 ingredients, and lists the 15 mL and US spoons separately.

Cooking Unit Converter
Convert between cups, spoons, millilitres, grams and ounces — with real ingredient densities, so a cup of flour and a cup of honey do not weigh the same.
What are you converting?
Starts at Australia's usual cup; your choice is kept. Spoons follow Australia: a tablespoon is 20 mL.
125 g per US cup · spooned and levelled — only used when converting between volume and weight
The same amount, every way
Weight figures assume flour, plain / all-purpose. Click any tile to copy it.
Australia rules and figures
- The Australian metric tablespoon is 20 millilitres, which is four teaspoons of 5 millilitres, not the three used in other countries.
- Australia has no pint or fluid ounce with an official size that could be found, so those units appear only among measures from other countries.
- The 20 millilitre tablespoon comes from Australian food sources, FSANZ and the ABS National Nutrition Survey, listed under the sources.
- Australian ovens use Celsius, so the temperature tab opens with 180 degrees and shows Fahrenheit, gas mark and fan values.

How the Cooking Unit Converter works
Everything is converted through millilitres for volume and grams for weight. Crossing between them uses the chosen ingredient’s density, taken from its weight in a US customary cup of 236.588 mL.
grams = mL × (grams per US cup ÷ 236.588); tablespoons = mL ÷ 20; fan oven °C = conventional °C − 20
- The Australian set is a 20 mL tablespoon of 4 teaspoons and a 5 mL teaspoon. No official Australian fluid ounce or pint is offered, so none appears in the local list.
- The cup starts as 250 mL. The US customary and US legal cups sit under other cup standards for imported recipes.
- One 20 mL tablespoon of butter at 227 g per US cup weighs 19.2 g, and 250 mL of granulated sugar at 200 g per US cup weighs 211.3 g.
- Under Measures from other countries you will find the 15 mL tablespoon, the US tablespoon and the imperial pint.
How to use the Cooking Unit Converter
- Enter the quantity. Type the amount as written in the recipe, for example 3 for three tablespoons.
- Select from and to. The first list is Kitchen measures in AU and starts with the 20 mL tablespoon. Pick a metric or weight target.
- Name what you are measuring. Choose the Ingredient for any conversion between a spoon or cup and grams.
- Compare with other spoons. To check a recipe from overseas, pick the 15 mL or US tablespoon in From and your local one in To.
- Convert the oven. On Oven temperature type a number and choose Celsius or Fahrenheit. The fan equivalent is 20 degrees lower.
Example: Three 20 mL tablespoons and a 250 mL cup in grams
Three Australian tablespoons are 60 mL, which is 4.06 US tablespoons and 4 tablespoons of 15 mL. One tablespoon of butter weighs 19.2 g, and two tablespoons of honey weigh 57.5 g. A 250 mL cup of granulated sugar weighs 211.3 g. An oven at 180 °C is 356 °F, gas mark 4, and 160 °C with a fan.
When to use the Cooking Unit Converter
- Cooking an American recipe. Convert US tablespoons to 20 mL ones, which are 35% bigger, before you measure out the spices.
- Sending a recipe overseas. Convert 20 mL tablespoons to millilitres so that someone using 15 mL spoons gets the same amount.
- Weighing ingredients for bread. Turn cups of flour into grams for a scale, using the weights tab for each flour.
- Setting a fan-forced oven. Enter the oven temperature in the recipe and read the fan setting 20 degrees lower.
What the Cooking Unit Converter does not do
- Ingredient weights are fixed single figures, mostly spooned-and-levelled. A packed cup of flour can weigh 20% more, so use them as a starting point.
- Only 50 ingredients are listed. Anything else, such as grated carrot or chopped onion, needs a weight from the packaging.
- The fan-oven setting is a flat reduction of 20 °C. Some ovens and recipes call for 25 °C.
- Volume units cover US, imperial, Australian and Indian katori sizes only; Japanese cups and metric spoons beyond the listed ones are absent. A pint or fluid ounce is not offered as a local unit in countries with no official size.
- The converter does not scale a recipe or change cooking times.
When something else is a better fit
- When you want to scale a whole recipe for more or fewer servings, use the Recipe Scaler.
- When you need general length, weight or temperature conversion, use the Unit Converter.
- When you need exact weights for baking science, use a kitchen scale and the weights printed by the recipe's author.
Questions about the Cooking Unit Converter
How big is an Australian tablespoon?
It is 20 mL, or four 5 mL teaspoons. A US tablespoon is 14.79 mL and a 15 mL one is common elsewhere, so a recipe using three spoons differs by up to a quarter.
How many grams is a tablespoon of butter?
19.2 g for a 20 mL tablespoon, derived from 227 g of butter per US customary cup. A 15 mL tablespoon of the same butter would be 14.4 g.
Is a metric cup 250 mL here?
Yes, the tool starts with a 250 mL cup for Australia. Change Cup standard to US customary (236.588 mL) or US legal (240 mL) when you follow a recipe from the United States.
What is a fan-forced oven setting?
The Oven temperature tab subtracts 20 °C from a conventional temperature. A 180 °C recipe becomes 160 °C. If food browns too fast, lower it again instead of shortening the time.
Why is there no Australian pint?
No official Australian pint or fluid ounce was found for this tool, so none is offered as a local unit. The imperial and US pints are still available under measures from other countries.
