No need really. The metric system is easy enough to learn. So if you need to know it, you pick it up in a heart beat. But yea, US schools' should start teaching the metric system.
But you all need to face facts that the Fahrenheit system is by far the best use for everyday use. Celsius piggy back on the wave of Metrication. What's dumb because Celsius isn't a real
SI unit. 0-100 unit system, nah, lets use a -17 to 37 for everyday use. That would be so much better. The boiling and freezing point of water isn't even universal.
But I guess one day the world is just going to force us to use Celsius. Using Celsius is BAD, and you should feel BAD!
And to the poster who said That would be salt water. Kinda like Fahrenheit's ice/salt mixture, which is...wait for it...
0 Fahrenheit. Oh snap! I'm glad we both agree Celsius is fail.
