I am so STOKED.

OK, metric in a nut shell. It is all based on the unit 10, which makes it hard for me having 9½ fingers, hence why i do have to wear jeans, unzip pretty much get close enough to 10 if you get the picture! No get that thought out of your head as you are going to have to try to sleep sometime tonight!

Temperature;
Based on water.
Water freezes at 0°C, water boils at 100°C. Makes sense and easier tha farenheit, right? A nice warm day 25°C. any hotter and you'll be lifting your kilt for the heat to escape.

Measurement;
1 kilometer (km) = 1000 meters (m) (kilo means thousand),
10 decimeters (dm) = 1 meter (deci is one tenth) we never use decimeters,
100 centimeters (cm) = 1 meter (centi is one hundreth) as in 1¢ = one hundreth of a dollar.
10 millimeter (mm) = 1 centimeter (milli is one thousandth)
so 1km = 1,000m = 10,000dm = 100,000cm = 1,000,000mm.

Weight:
Again based on water.
1 liter(L) of water = 10cm x 10cm x 10cm of volume so a cube of water 10 cm long, wide and deep (1000 cubic centimeters or 1000cm³).
Now that 1 liter of water weighs exactly one kilogram (kg), which is 1000 grams (g), therefore 1 cm³ of water weighs 1 gram.
Now 1000kg (or 1000 liters of water) = 1 tonne (1 metric ton).

Clear as mud, right?
