Using metric in WeatherBlur

When we take measurements for WeatherBlur we use the international measurement system, that all scientists use – that is metric.

  • Distances are measured in meters (m)
  • Volumes are measured in liters (l)
  • Mass is measured in grams (g)
  • Temperatures are measured in degrees Celsius. (C)
  • Pressure is measured in pascals (Pa)
  • Energy is measured in joules (J)
  • Time is measured in seconds (s)

Metric is a very simple system to use because it uses base-10 (i.e. all the units are either 10, 100 or 1000 etc) for all its measurements.  A unique prefix is given for each order of magnitude:

Kilo-          Hecto-          Deca-          BASE          Deci-          Centi-          Milli-

1000 X     100 X              10 X                                   1/10 X          1/100 X        1/1000 X

So for example, when we measure distance we use meters.  If the measurement is 1000 meters it is called a kilometer.  If the measurement is a thousandth of a meter it is called a millimeter.  Distances between towns would be measured in kilometers.  The thickness of a shell would be measured in millimeters.

The only exception to this is time – which is measures in seconds, hours, days etc.

In the metric system there are some easy to learn relationships like these:

1 liter of water weights 1 kilogram.

Water freezes at 0oC

Water boils at 100oC
