Although polar and the spherical coordinates uses radians to describe coordinates in 2 and sometimes 3 dimensions. 01 Overall summary; 2.04 SI units for angular measurement There are two other derived SI units. A wheel makes 360 revolutions in 1 minute. We define radian in terms of length of arc : Angle subtended by an arc of 1 unit in a circle of radius 1 unit is 1 radian . Steradian is the angle subtended, at the center of a sphere, by a surface whose magnitude of area is equal to square of the radius of the sphere.The solid angle of a sphere at it s centre is 4π steradians. The unit is derivable from the radius coordinate, so the angle measure is still without any dimension. Contact. Radiant Physics Inc.

"Journey of thousands mile start with a single step." The radian is the SI unit for measuring angles. Units A definite amount of a physical quantity is taken as its standard unit. The steradian (symbol: sr) or square radian is the SI unit of solid angle.It is used in three-dimensional geometry, and is analogous to the radian, which quantifies planar angles.Whereas an angle in radians, projected onto a circle, gives a length on the circumference, a solid angle in steradians, projected onto a sphere, gives an area on the surface. The SI derived units for these derived quantities are obtained from these equations and the seven SI base units.
