KONVERSI SATUAN Konversi = mengubah. Kelebihan sistem Satuan Internasional (SI) adalah kemudahan dalam pemakaiannya karena menggunakan sistem desimal (kelipatan 10) dan hanya ada satu satuan pokok untuk setiap besaran dengan penambahan awalan untuk satuan yang lebih besar atau lebih kecil. Misalnya, 1 centimeter = 0,01 meter atau 1 kilogram sama dengan 1000 gram. Besaran apapun yang kita ukur, seperti panjang, massa atau kecepatan, terdiri dari angka dan satuan. Sering kita diberikan besaran dalam satuan tertentu dan kita kita ingin menyatakannya dalam satuan lain. Misalnya kita mengetahui jarak dua kota dalam satuan kilometer dan kita ingin mengetahui berapa jaraknya dalam satuan meter. Demikian pula dengan massa benda. Misalnya kita mengukur berat badan kita dalam satuan kg dan kita ingin mengetahui berat badan kita dalam satuan ons atau pon. Untuk itu kita harus mengkonversi satuan tersebut. Konversi berarti mengubah. Untuk mengkonversi satuan, terlebih dahulu harus diketahui beberapa hal yang penting, antara lain awalan-awalan metrik yang digunakan dalam satuan dan faktor konversi.

The Newton is the unit of force of the SI. A Newton is the force required to give to a mass of 1 kilogram an acceleration of 1 meter per second. The most current force is the weight. It is a vertical force directed to the bottom, which results from the action of gravity. Whose equivalent is : mass * 9.806 (N/kg) ) Pression (the unit of pressure of the S.I is the Pascal) The pressure is a force per unit of area.

A Pascal corresponds to the pressure generated by a force of 1 Newton acting on a surface of 1 square meter also said Newton per square meter (N/m2). It is a rather small unit like result and it more often used as a kilopascal [ kPa ] or in bar, equivalent to 100 000 Pascal. Le daN is the 1/10 of N , et le daN/cm2 is equal to 1 bar. 

ENERGIE, TRAVAIL ou QUANTITE DE CHALEUR

Joule (J) is equivalent to the work produced by a force of 1 Newton who's the point of application moves of 1 m in the direction of the force. The calorie that is still used is quantified under various values. The general standard, it is the quantity of heat necessary to raise 1°C the temperature of 1 gram of water of 14.5 to 15.5°C under the normal atmospheric pressure. 1 calorie = 4.186 J - 0.003968 Btu - 3.087 foot-pounds. 

1 kg of water at 15°C under 1 atm = 4.1855 kj/kg °C or 1 kcal/kg °C · 1 kcal = 1.163 w.



The small calorie or therm, is measured of 3.5°C to 4.5°C (water is densest at 4°C).

The intermediate value of the calorie in the range of 0°C to 100°C is called the average calorie; i.e. 1/100 of energy necessary to heat the water of 1 gram of water of the melting point at its point of boiling. Type of calorie Thermochemical International Table at 15 °C Mean of 0°C to 100°C

A British thermal unit (Btu or BTU and also known as a heat unit in the United States) BTU: It is the quantity of heat necessary to increase the temperature of a degree Fahrenheit per unit of mass of 1 pound of water, that is to say a mass of 0.4535924 kg. The British Thermal Unit (BTU) can also take various values and are called in a similar way to the calorie, that is Btu (IT), (Th), etc. One hundred thousand BTU (100 000 Btu) are called a Therm , thus its exact value depends on which BTU is used.

Energie mesurée en unité de temps (unités non conventionnelles) Le Joule étant une unité trop petite pour les besoins usuels, on utilise plutôt Watt-heure (Wh) ou son multiple le kilowatt-heure (kWh) (C'est le cas général par exemple pour les calculs de bilans thermiques ou calculs de déperditions) 1 Mega-joule (MJ) 1 Watt-heure (Wh)

= 278 Wh ou 0,278 kWh = 3600 Joules

1 calorie/heure (cal/h) (unité non usitée) = 0,0011639 Wh 1 British thermal unit/hour (Btu/h)

Power (the unit of power of the S.I = Watt) The power is the unit of energy per unit of time. 

1 Joule = 1 Watt during one second.



1 Joule (J) = 1 w/s or Newton meter (Nm).



1 watt/h = 3600 Joules.

C'est cette unité qui est attribuée aux générateurs d'énergie (moteurs, chaudières, etc.) ou à leurs dérivés. 

1 Watt = 1 Joule pendant une seconde.

Energie (E en Joules) = W (Puissance en watt) x t (temps en secondes) Par exemple : 

Une ampoule de 100 W (puissance) sera équivalent en énergie (E) sur une heure à 0,36 MJ ou 100 Wh.



Un moteur d'une puissance de 10 ch (7,36 kw) sera équivalent en énergie (E) sur une heure à 26,5 MJ ou 7,36 kWh.

Attention ceci ne signifie pas la consommation d'énergie (Il faut intégré tous les rendement et autres pour obtenir la consommation d'énergie équivalente) Il y a 2 unités différentes dans l'utilisation du horse power (HP). La pemière unité (HP = 745,7 watt) utilisée au USA/UK est basée sur l'énergie équivalente pour soulever un poids de 550 livres (pound) au travers 1 pied (foot) en une seconde. La seconde unité (HP = 736 watt) utilisée en Europe continentale est basée sur l'énergie équivalente en énergie à soulever dun poids de 75 kilogrammes sur 1 mètre en 1 seconde.
