Energy Conversion

Equals

Important Notes
  • In the International System of Units (SI), the unit of energy is the joule. It is equal to the energy expended (or work done) in applying a force of one newton through a distance of one meter.
  • Energy can also be expressed in many other units that are not part of the SI such as ergs, calories, British Thermal Units, kilowatt-hours and kilocalories, which require a conversion factor when expressed in SI units.
  • The SI unit of energy rate (energy per unit time) is the watt, which is a joule per second. Thus, one joule is one watt-second and 3600 joules equal one watt-hour.
  • The CGS energy unit is the erg and the imperial & US customary unit is the foot pound. Other energy units such as the electronvolt, food calorie or thermodynamic kcal (based on the temperature change of water in a heating process) and BTU are used in specific areas of science and commerce.
  • Energy is essential to life and all living organisms. The sun, directly or indirectly, is the source of all the energy available on Earth.

Energy

In physics, energy is the quantitative property that must be transferred to an object in order to perform work on or to heat the object. The SI unit of energy is the joule which is the energy transferred to an object by the work of moving it a distance of 1 meter against a force of 1 newton.
Common forms of energy include the kinetic energy of a moving object, the potential energy stored by an object's position in a force field (gravitational, electric or magnetic), the elastic energy stored by stretching solid objects, the chemical energy released when a fuel burns, the radiant energy carried by light and the thermal energy due to an object's temperature.

Currency is a medium of exchange for goods and services. A more general definition is that a currency is a system of money (monetary units) in common use, in the form of paper or coins, usually issued by a government especially for people in a nation.

Percentages
Percentages Calculator

The term "percent" is derived from the Latin per centum, meaning "by the hundred". A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%" or the abbreviations "pct.". Percentages are useful for comparing information where the sample sizes or totals are . . . .

Pressure
Pressure Converter

Pressure (symbol: p or P) is the force applied perpendicular to the surface of an object per unit area over which that force is distributed. Gauge pressure is the pressure relative to the ambient pressure. Unit of pressure is Pascals (Pa). Types of Pressures are Absolute, Atmospheric, Differential, Gauge Pressure etc. Atmospheric . . . .

Mass
Mass Converter

Mass is both a property of a physical body and a measure of its resistance to acceleration (a change in its state of motion) when a net force is applied. An object's mass also determines the strength of its gravitational attraction to other bodies. The basic SI unit of mass is the kilogram (kg). In physics, mass is . . . .

History of Measurement :

The earliest recorded systems of calculations and measures originate in the 3rd or 4th millennium BC. Even the very earliest civilizations needed measurement for purposes of agriculture, construction and trade. Early standard units might only have applied to a single community or small region, with every area developing its own standards for lengths, areas, volumes and masses.

With the development of manufacturing technologies and the growing importance of trade between communities and ultimately across the Earth, standardized weights and measures became critical. Starting in the 18th century, modernized, simplified and uniform systems of weights and measures were developed, with the fundamental units defined by ever more precise methods in the science of metrology.
