How To Do English to Metric Conversion

It can be confusing having to cook with metric measuring utensils when the recipe is in Imperial. Now learn how to convert.

1. Go from Imperial to Metric and back again. If you have time to consult this article, you can always check your conversions here. Or print out a list of your most commonly used conversions and keep it with your recipes (probably a more practical idea).
   
   • 1/4 tsp.=1ml
   • 1 tsp.=5ml
   • 1 tbsp.=15ml
   • 1 fl. oz.=30ml
   • 1/4 c.=60ml
   • 1/2 c.=8 tbsp.
   • 3/4 c.=12 tbsp.
   • 1 c.=16 tbsp.
   • 1 oz.=28g.
   • 1 lb.=455g.
2. What is the formula? Well this is complicated, but there are some commonalities. For instance if you remember that 1ml=1g., it can help you know that 1oz and 1fl. oz. are 28ml and 30ml respectively. But if all you can remember is that 1oz = 30ml then it won't make much difference when you're cooking if you interchange these measurements.
3. A difference of a couple of ml will almost never affect a recipe, so if you cannot remember the exact measurements then use an estimated guess such as: 1/4 tsp.=1ml so a full cup must equal 4ml (which is close enough to 5ml).

It can sometimes be a good idea to have measuring utensils in both metric and imperial systems to avoid having to do the conversion.
