Important Notes
  • A hexadecimal color is specified with: #RRGGBB. RR (red), GG (green) and BB (blue) are hexadecimal integers between 00 and FF specifying the intensity of the color.
  • RGB values are usually given in the 0–255 range; if they are in the 0–1 range, the values are multiplied by 255 before conversion. This number divided by sixteen gives the first hexadecimal digit (between 0 and F, where the letters A to F represent the numbers 10 to 15). The remainder gives the second hexadecimal digit. For instance the RGB value 201 divides into 12 groups of 16, thus the first digit is C. A remainder of nine gives the hexadecimal number C9. This process is repeated for each of the three color values.

Color

Color or colour is the characteristic of visual perception described through color categories with names such as red, orange, yellow, green, blue or purple. Web colors are colors used in displaying web pages on the World Wide Web and the methods for describing and specifying those colors.
Colors may be specified as an RGB triplet or in hexadecimal format (a hex triplet) or according to their common English names in some cases. A color is specified according to the intensity of its red, green and blue components, each represented by eight bits. Thus, there are 24 bits used to specify a web color within the sRGB gamut and 16,777,216 colors that may be so specified.

Angle
Angle Converter

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 . . . .

Triangles
Triangles (Perimeter & Area)

A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. In Euclidean geometry, any three points when non-collinear, determine a unique triangle and simultaneously, a unique plane (i.e. a two-dimensional Euclidean space). In other words, there is only one plane that . . . .

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.
