Conversion of Common Measurement Units and Quantity and International Unit System (SI)
International Unit System
International Unit System (SI) is a benchmark that regulates the unit, the measurement quantity and the relationship between the two. This system is recognized globally and was formed in 1960. SI sets the unit for each measurement quantity, but basically all units and quantities, based on 7 quantities and 7 measurement units respectively, namely: mass (kilogram), length (meter), time (seconds), electric current (amperes), temperature (Kelvin), number of units of substance (moles), and luminousity (candela). Here you can try how the SI base unit relates to other units for each quantity.
Length Conversion >>
Length is a term to measure distance quantity. In the International System of Quantities, length is a quantity with measurement range. In many systems of measurement a base unit for length is chosen, from which all other units are derived. In the International System of Units (SI) system the base unit for length is the meter.

Electricity Current Conversion >>
An electrical current is a stream of charged particles, such as ions or electrons, moving through an electrical conductor or area. It is measured as the net rate of flow of electric charge past a region. The moving particles are called charge providers, which may be among several types of particles, depending upon the conductor. In electric circuits the charge providers are often electrons moving through a wire. In semiconductors they can be electrons or holes. In an electrolyte the charge providers are ions, while in plasma, an ionized gas, electrical current is formed by both ions and electrons.
