Important Notes
  • The degree, denoted by a small superscript circle (°), is 1/360 of a turn, so one turn is 360°. Among all units, the degree and the radian are by far the most commonly used.
  • The radian is the angle subtended by an arc of a circle that has the same length as the circle's radius. One turn is 2π radians and one radian is 180 / π degrees or about 57.2958 degrees. Angles expressed in radians are dimensionless for the purposes of dimensional analysis and its applications.
  • The turn, also cycle, full circle, revolution and rotation is complete circular movement or measure (as to return to the same point) with circle or ellipse. A turn is abbreviated τ, cyc, rev or rot depending on the application but in the acronym rpm (revolutions per minute), just r is used.
  • The quadrant is 1 / 4 of a turn, i.e. a right angle. 1 quad.=90°=π/2 rad=1/4 turn=100 grad. Also, The sextant (angle of the equilateral triangle) is 1 / 6 of a turn and The grad, also called grade, gradian, or gon, is 1 / 400 of a turn, so a right angle is 100 grads.

Angle

In plane geometry, an Angle (Latin word angulus, meaning "corner") is the figure formed by two rays called the sides of the angle, sharing a common endpoint called the vertex of the angle.
Angle is also used to designate the measure of an angle or of a rotation. This measure is the ratio of the length of a circular arc to its radius. In the case of a geometric angle, the arc is centered at the vertex and delimited by the sides. In the case of a rotation, the arc is centered at the center of the rotation and delimited by any other point and its image by the rotation.

Interest Calculator

Interest, in finance and economics, is payment from a borrower or deposit-taking financial institution to a lender or depositor of an amount above repayment of the principal sum (that is, the amount borrowed), at a particular rate. Interest differs from profit, in that interest is received by a lender whereas profit . . . .

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 . . . .

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 . . . .

Power Converter

In physics, power is the amount of energy transferred or converted per unit time. In the International System of Units, the unit of power is the watt, equal to one joule per second. In older works, power is sometimes called activity. Power is a scalar quantity. The output power of a motor is the product of the torque that the motor . . . .

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.
