calorie

The calorie is a pre-SI unit of energy, in particular, heat. In most fields, its use is archaic, and the SI unit of energy, the joule, has become accepted. However, it remains in common use as a unit of food energy. It was first defined by Professor Nicolas Clément in 1824 as a kilogram-calorie, and this definition entered French and English dictionaries between 1841 and 1867. Etymology: French calorie, from Latin calor (heat).

The unit calorie has historically been used in two major alternate definitions that differ by a factor of 1000:

Celsius is easy

Celsius temperature is easy for an American to learn. The way to success is NOT to convert, but to get used to interpreting Celsius readings. Zero degrees C is the freezing point of water, so ice forms--or melts---at 0 C. Single numbers to teens are chilly to cool. Room temperature, or a comfortable day outdoors, would be in the low 20s. Over 30? A very warm to hot summer day. Normal body temperature is a toasty 37. Water boils at 100.

Measuring Distance in Japan - The Metric Way


japanese girls - metric sytem		 rejection of the metric system is a mystery

Those planning to travel, for business or pleasure will do well to learn the system of length conversion known as the metric system. In fact, a knowledge of metric length conversion will serve you well wherever you go on the planet, since only three countries in the world - Liberia, Myanmar and the U.S. - have refused to accept the metric system. (In the U.S., rejection of the metric system cost NASA $125 million dollars when a valuable Mars probe was lost back in 1999, because the scientists were working with two different measurement systems.)

Sphere of influence - silicon 28

metric sphere

120 year old cylinder that defines the world standard for one kilogram to be replaced by sphere of silicon 28

The 120 year old International Prototype that defines the world's standard for the mass of one kilogram, held at the International Bureau of Weights and Measurement in Paris (BIPM), is set to be replaced by a perfect silicon crystal sphere developed by scientists at Australia's CSIRO. According to the CSIRO, the international scientific community, under the auspices of the BIPM, decided to focus on several methods for redefining the kilogram. One of those was the Avogadro Project that sought to bring together enough atoms of one substance to make the perfect kilogram. The sphere was made from one isotope: silicon 28.
