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 | 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.

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

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 | 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.

Example

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.

Example

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.

Recipe Conversion | US to British and British to US quick conversions.

Many US and British recipes give measurements in metric ml, in which case Recipe Conversion is not needed.

The US fluid ounce is only a little different to the US fluid ounce so for most recipes Recipe Conversion is unnecessary and they can be considered the same.

The US teaspoon and tablespoons are only a little different to the British metric teaspoon and tablespoons so again for most recipes Recipe Conversion is unnecessary and they can be considered the same. The only issue here is if the units are actually imperial tablespoon (17.7581714 ml) or imperial teaspoon (5.91939047 ml).

US and British pints do differ quite a lot, US=473.18 mL British=568.26 ml. The table below shows the direct conversion factors to use.

The US cup is 8 US fluid ounces (fl oz) or 236.59 ml. The British cup is 10 British fluid ounces (fl oz) or 284.1 ml. Therefore the British cup is approximately one fifth greater than the US equivalent. The table below shows the conversion factors to use to directly convert between the two.

So the Recipe Conversion for a British recipe containing 5 British Cups would equal 5 * 0.83 = 4.15. Recipe Conversion need not be this exact so we just say 4 and a bit cups.

This Recipe Conversion method will allow you to convert any weight/mass, volume or length ingredient unit into any other ingredient unit. The method works by giving you the conversion factor for a common unit (metric), you can then convert from that unit back into any other unit.

Recipe Conversion | Weight / Mass Conversion

To convert any Weight measure in to any other other weight measure first convert it to grams and then convert it to the desired unit.

Example: To convert 10 Pounds (lb) to milligrams (mg) using this method, first convert 10 Pounds to grams, 10 * 453.59 = 4535.9 Next convert 4535.9 grams into milligrams, 4535.9*1000 = 4535900mg.

If you would like a program that does all the hard work for you, you can download one free here Recipe Converter.

Recipe Conversion | Length Conversion

To convert any length measure into any other other length measure first convert it to grams and then convert it to the desired unit.

Example: To convert 10 Inches (“) to metres (m) using this method, first convert 10 Inches to millimetres, 10 * 25.4 = 254.0 Next convert 254 millimetres into metres, 254*0.001 = 0.254metres.

A small downloadable program is available that will make this Recipe Conversion much easier for you, you can find it here Recipe Converter.

Recipe Conversion | Volume Conversion

To convert any volume measure into any other other volume measure first convert it to millilitres and then convert it to the desired unit.

Example: To convert 1 UK pint to litres (l) using this method, first convert 1 UK Pint to millilitres, 1 * 568.26 = 568.26 Next convert 568.26 millilitres into litres, 568.26*0.001 = 0.56826 litres.

Tc = (5/9)*(Tf-32)

Tc is the temperature in degrees Celsius (°C) and Tf is the temperature in degrees Fahrenheit (°F)

To convert from degrees Celsius (°C) to degrees Farenheit (°F) , you need to do the following calculation.

Tf = (9/5)*Tc+32

Tc is the temperature in degrees Celsius (°C) and Tf is temperature in degrees Fahrenheit (°F)

To make this all simpler Recipe Conversion have a small downloadable program Recipe Converter.
