We had a couple of comments recently regarding a need to convert between metric (ml, liters, kilos) and Imperial measures (cups, teaspoons, pounds) If you're reading this blog on the net, you already have a simple way to convert from almost any measure to any other at your disposal - Google.
Go to Google and search for "500 ml in teaspoons". Google recognizes you're asking for a conversion, not a search result, and you'll discover it's 101.442068 teaspoons. Hm. That's a lot of teaspoons. Maybe that'd be better in ounces? "500 ml in ounces" gives us a search result of "500 ml = 16.9070113 US fluid ounces". In cups? "500 ml in cups" gives us "500 ml = 2.11337641 US cups". Much more useful. We can even make all those digits more useful ".11337641 cups in teaspoons" yields ".11337641 US cups = 5.44206768 US teaspoons"
It'll even help you remember the conversions within the Imperial system. Type in "1 cup in tablespoons", a conversion few of us do often, and you'll discover that 16 tablespoons go into a cup. That's why you generally see 3 tablespoons of an ingredient or a 1/4 cup.
Google has all kinds of tricks like this, but I find the units conversion one to be very helpful. Heck, if you live in the U.S. and type in "Mycityname weather", it'll give you a brief weather outlook to let you know if it's a good day to plan to bake all day or to head to the beach.
It's going to be 42 F in Chicago today. Oh, and Google tells me that's 5.55 C.
