Introduction: Metrication of Recipes Simplified
America is still using Imperial Measurements in their recipes. There are 6.4 billion Metric users vs. only .3 billion Americans. So this is a four step, when you use your Metric Cups/Spoons, process to convert your American recipes to Metric.
When I first made my first Metric instructable there was virtually no one selling Metric Cups and Spoons. As of 8/7/2010 I have found now only three websites selling to Americans, True Metric Cups and Spoons, and you should spend no more then $5. Replacing your American cups, 237 mL for a Metric cup, 250 mL, and Replace your American tablespoon set, 14.79 mL with true Metric tablespoon set, 15 mL.
Next you need to do, is substitute every American pound (453.59 g) with 500 g. That was easy, no? You will need to convert centimeters, and Celsius. In the end you will actually end up making about 10% more. Why? Because the Metric Kitchen units are bigger then the American units.
Metric is easy -- one gram of water = one milliliter of water = one cubic centimeter.
Water --- 1 g = 1 mL = 1 cm³
1 kg = 1 L = 1 dm³
1 Mg = 1 kL = 1 m³

Step 1: Choose Your Faviorite Recipe
So You Want to Convert Your Recipe to Metric And You Want to Use Weights With Your Dry Ingredients? How Do You Do It?
Are You Confused and Baffled?
It is a Four Step Process, if you use Metric cups/spoons, That You Have To Follow
First, you do not have to change the cups and spoon measurements keep them exactly the way they are. But add the words 'This is a Metric Recipe with one cup = 250 mL'
Remember the following ...
One cup = 250 mL
Half cup = 125 mL
Quarter cup = 60 mL (62.5)
Eigth cup = 30 mL (31.25)
One tablespoon = 15 mL
One teaspoon = 5 mL
Step 2: Convert Solid Weights
Convert all English Weights to Grams or Kilograms.
Use 500 g for every one pound as the formula and
Use 31.25 g for every dry ounce
You can also use 31.25 mL for every fluid ounce
In this recipe you would actually now replace 1.5 lbs with 750 g, not the exact grams replacement.
Here is a quick review of exact equivalent...
one ounce equal 28.3 g
one pound equal 453.6 g
Five pounds equal 2.27 kg or 2267.96 g
one fluid ounce equal 29.57 mL
OK, how did I come up with 31.25 for both dry and fluid ounce, you may ask?
For comparison and to keep inline with my Metrication of Recipes...
one American pound divide by 16 to get dry ounces
-- 500 g (1/2 kg) divide by 16 to get 31.25 grams
one American quart divide by 32 to get fluid ounces
-- one liter divide by 32 to get 31.25 milliliters
Step 3: Convert Temperatures
Convert All Fahrenheit Temperatures to Celsius
Use the Conversion Calculators
0°F ≈ -18°C
32°F = 0°C
150°F ≈ 66°C or round down 65°C
175°F ≈ 79°C or round up 80°C
300°F ≈ 148°C or round up 150°C
350°F ≈ 177°C or round up 180°C
475°F ≈ 246°C or round down 245°C
Step 4: Convert Lengths
Convert all English Length Measurements to
Centimeters and Millimeters. Use Conversion Calculators.
1/8 inch ≈ 3 mm
1/4 inch ≈ 6 mm
1/2 inch ≈ 13 mm
3/4 inch ≈ 19 mm
1 inch ≈ 2.5 cm
5 inch ≈ 13 cm
10 inch ≈ 25 cm
Step 5: Convert Dry Volumes
Get out your new scale and weigh all dry ingredient volumes to find the weight in Grams, but leave any dry ingredient that measures a tablespoon or less, in Milliliters. Again, there are charts out there to convert the different dry ingredients directly from volume to weight but there just too many variables. It is best to weight it yourself for accuracy.
This is an optional step but well worth the effort...
You want to use weight vs. volume measurements because of ingredients like, flour, does not matter if it is shifted, leveled, or packed. For this recipe, how many crackers does it take to make 3/4 cup? Easy, weigh it first, then crush them! Does you sugar need to be packed? NO.
Weight to volume calculators, they already have the density value added for each ingredient (remember these are now Metric Cups).....
Not every food member are on the list of these calculators, for example, carrots is not there. To solve that issue see my Finding the Density of Food You Eat instructable.
America is still using Imperial Measurements in their recipes. There are 6.4 billion Metric users vs. only .3 billion Americans. So this Four step process will help you to convert your American unit recipes to Metric units. Now you can easily exchange recipes with people from Canada, Mexico, and the rest of the World.
You will need...
an electronic scale
a Kilogram set to calibrate your scale
a 30 cm ruler
Metric cups and spoons set
Metric meat and candy thermometers
Timers (Metric Time anyone?)
