opettaja.jpgIn physicsstrength calculations and between different things the units should be common. This means the SI -system for determining the calculation tasksThe system consists of seven basic unitsLength, mass, electric currenttime, temperatureamount of substance, and luminous intensity.

The calculation can not be performed if the calculation is not realized in the form of unitsTherefore, it is to think about which units are used in the calculationAfter this, the calculation has the mathematical harmony, this because the events are of the Big Bang and processed through the energy expressions.

 

Many of the tabulated quantities are related to energy.

Mass                                                     m                     kg                 kilogram

Time                                                       t                       s                  second

Electric current                                       I                       A                  ampere

Thermodynamic temperature                T                       K                  Kelvin

Amount of substance                             n                     mol                 mole

Luminous intensity                                 I                       cd                  candela

CGPM The General of Weights and Measures Conference

All others except the kilogram are defined based on natural phenomena. A kilogram (kg) is based in France, to late 1700's specified prototype piece. EP-calculation expandthe concept of the above quantitiesWhen calculating the value of kg is converted by the coefficient of 9.82 kg to the value N (Newton = 0.102 kg). The value of 1 kN means in practice 100 kg mass.

If necessary, the units are related to the calculation in a suitable formby the model of physics. By using the tables, it is possible calculate tasks without converting unitsFor example, 1 mile (1.609 km) has the golden section ratio (1.618) compared to kilometer (error 0.0055%).

Inch 2.54 cm is 1.6182 = 2.618        (error 0.03%).

2.618 / 1.03 = 2.54

In some cases, it may determine the percent error of 0.03 as the universal friction 1.03. This is time dilation value when the speed is 0.25 x c and which belongs almost to all phenomena calculation. By controlling the proportional equivalent calculation, measure conversion is not required in different units of the calculationThis requires awareness of the values ​​formation.
