When people search for Recipe Conversion they are generally looking at converting an existing recipe to meet their needs. There are a number of different types of Recipe Conversion.
- Recipe Conversion to change the units from imperial to metric and metric to imperial.
- Recipe Conversion to make more or less portions/servings.
- Recipe Conversion to change to more useful units
- Recipe Conversion because of Country differences
- Recipe Conversion to fit certain size cake tins, baking trays etc.

Recipe Conversion | Imperial to Metric and Metric to Imperial
To convert weights and measures from Metric to Imperial or Imperial to Metric all we do is multiply by the appropriate factor. The table below shows the conversion factors to use.
|To Convert||Multiply By|
|Pounds (lb) to grams (g)||453.6|
|grams (g) to Pounds (lb)||0.002205|
|Pounds (lb) to KiloGrams (kg)||0.4536|
|kilograms (kg) to Pounds (lb)||2.205|
|Ounces (oz) to grams (g)||28.35|
|grams (g) to Ounces (oz)||0.03527|
Recipe Conversion | Example
To convert 4 pounds (lbs) to grams we multiply by 453.6 and get 1814.4 grams. (4 * 453.6 = 1814.4)
Things get a little tricky if you have a weight in pounds and ounces. First multiply the pounds value to grams, then multiply the ounces value
to grams and add the two results to get your final answer.
Recipe Conversion | Imperial to Metric and Metric to Imperial Lengths
Occasionally you may need to do Recipe Conversion on lengths of ingredients. Here are the Conversion Factors
|To Convert||Multiply By|
|Inches (“) to Centimetres (cm)||2.54|
|Centimetres (cm) to Inches (“)||0.394|
|Inches (“) to MilliMetres (mm)||25.4|
|MilliMetres (mm) to Inches (“)||0.039|
Recipe Conversion | For Changing Portions or Servings
To do Recipe Convenversion due to wanting to change portions or serving sizes of a Recipe first we note the portions/servings of the orignal recipe and the portions/serving of the new recipe we would like to make.
In the example above, the Original Recipe has 10 Portions (Cookies) and the New Recipe has 15 Portions (Cookies).
Now we divide our New Recipe Portions by the Original Recipe Portions. So 15 / 10 = 1.5
Therefore to do the Recipe Conversion you need to multiply all the original recipe ingredient quantities by 1.5.
For example if the original recipe says 100 grams of sugar, then 100 grams multiplied by 1.5 = 150grams. So you need 150grams in your new recipe. As you can see Recipe Conversion for portions iszes is fairly simple.
Recipe conversion sometimes requires some simple mathematics. The mathematics of converting a square or circular baking tray or tin to a larger diameter aren’t so straight forward. To do this try of Recipe Conversion follow the simple steps outlined here.
Recipe Conversion | Changing for Square or Rectangular Items
For Square or Rectangular Recipes the following Recipe Conversion can be used.
Note: This calculation assumes you want to keep the height/depth of the cake/pizza/loaf/whatever the same. If you do not you will have to further multiply by the depth also and think about changing cooking times.
Before we can do the Recipe Conversion we need to know the width and length of the original recipes tin/pan/pot and the width and length of the new recipes tin/pan/pot. The Width is across one side of the rectangle and the Length is across the other side of the rectangle, it doesn’t really matter which way round you measure it as long as you don’t measure the height.
Original Recipe Length = 23 Inch, Width = 13 Inch
New Recipe Length = 28 Inch, Width = 15 Inch
All measurements must use the same measurment scale. The above example uses all inches.
The next stage of this Recipe Conversion is to calculate the area of each Recipes rectangle.
To calculate the area we simply multiply the Length by the Width (Area = Length * Width)
So the Orignal Area will be 23 * 13 = 299
We now calculate the area of the New Recipe, this will be 28 * 15 = 420
And next we divide our new area by the old area. 420 / 299 = 1.4
Therefore to do the Recipe Conversion you need to multiply the Original Recipe quantity by 1.4.
For example if the Original Recipe says 100grams of Sugar. Then 100grams * 1.4 = 140grams. So you need 140grams in your new recipe.
Recipe Conversion | Changing the Recipe for Circular Items
For Cakes and Pizza the following can be used.
This calculation assumes you want to keep the height/depth of the cake/pizza/loaf/whatever the same. If you do not you will have to further multiply by the depth also and think about changing cooking times.
Before we can do this Recipe Conversion we need to know the diameter of the original recipe and the diameter of the new recipe. The Diameter is the distance across the widest part of the circle.
Original Recipe Diameter = 9 Inch
New Recipe Diameter = 12 Inch
The next stage of this Recipe Conversion is to calculate the area of each Recipe.
To calculate the area we multiply the diameter by p (Area = Diameter * p)
Don’t be scared by the mathematical symbol p. The p is just the symbol for pi (no not pie but pi). Pi or p is just a mathematical constant. This means it has a value and pi’s value is 3.142 (well thats not exact but it will do for Recipe Conversion purposes). So back to calculating we replace pi or p with 3.142.
Recipe Area = Diameter * 3.142
So the Orignal Pizza Area will be 9 * 3.142 = 28.278
We now calculate the area our new recipe will have. 12 * 3.142 = 37.704
And next we divide our new area by the old area. 37.704 / 28.278 = 1.333
Therefore to do the Recipe Conversion you need to multiply the Original Recipe quantity by 1.333.
For example if the Original Recipe says 100grams of Sugar. Then 100grams * 1.33 = 133grams. So you need 133grams in your new recipe. Just multiply all the other ingredients in the same way to finsih your Recipe Conversion.
