Conversion Unit in Physics Lesson

 In addition to the metric system unit, also known as the other units are often used in everyday life, such as liters, inches, yards, feet, miles, tons and ounces. Units can be converted or transformed into the metric system units with a specified benchmark. Length scale conversion using the reference as follows:

  1 mile = 1760 yards (1 yard is the distance of the shoulder to the tips of the fingers of adults).
    1 yard = 3 feet (1 feet is the distance heel to toe adult).
    1 feet = 12 inches (1 inch is the maximum width of an adult's thumb).
    1 inch = 2.54 cm
    1 cm = 0.01 m
Units of miles, yards, feet, inches is called the English system units. To apply the system of mass scale conversions of units daily and the English system into the SI system. For example as follows.

    1 tonne = 1000 kg
    1 ounce (oz) = 0.02835 kg
    1 quintal = 100 kg
    1 pound (lb) = 0.4536 kg
    1 slug = 14.59 kg
Units of time in everyday life can be converted into the SI system that is second or seconds. For example as follows.

    1 year = 3.156 x 10 ^ 7 seconds
    1 hour = 3600 seconds
    1 day = 8.640 x 10 ^ 4 sec
    1 minute = 60 seconds

The size of derivatives has units that are translated from the unit quantities that define the principal amount of such derivatives. Therefore, it is often found growing unit quantities can be derived more than one because of different definitions penjabarannya. For example, the unit of acceleration can be written m / s ^ 2 can also be written with N / kg. Unit size can also be converted derivatives. Consider some examples below!

    1 dyne = 10 ^ -5 newtons
    1 ERG = 10 ^ -7 joules
    1 calorie = 0.24 joules
    1 kWh = 3.6 x 10 ^ 6 joules
    1 liter = 10 ^ -3 m ^ 3 = 1 dm ^ 3
    1 ml = 1 cm ^ 3 = 1 cc
    1 atm = 1.013 x 10 ^ 5 pascals
    1 gauss = 10 ^ -4 tesla

Main scale and magnitude of Derivatives

The quantity in Physics grouped into two, namely the amount of principal and the amount of derivatives. Magnitude is the amount of principal that have been defined beforehand. Derived magnitude scale is derived from fundamental quantities. System unit scale of Physics in principle be standard or standard, that is fixed, universally applicable, and can easily be used at all times appropriately. Standardized system of units set in 1960 by a meeting of scientists in Sevres, Paris. System of units used in education and knowledge is called the metric system, which are grouped into large metric system or the MKS (Meter Kilogram Second) called the international system or abbreviated SI and metric systems of small or CGS (centimeter Gram Second). Basic scale and magnitude of the derivative along the unit can be seen in the following table.
