Well, that is neat. When using metric and celsius:

• 1 kilometer is 1.000 meters.
• 1 square meter of water weighs exactly 1 tonne. (1.000 kilo also known as a kilokilo)
• The vastly superior metric dozen is exactly 10.
• Water freezes at exactly 0 degrees.
• 1 meter of water takes exactly 100 minutes - a metric hour - to completely evaporate when heated to 100 degrees. Doing so requires exactly 1 kilowatt of power.
