Why the word or unit radian can be omitted when an angle is measured in radian?

As the ratio of two lengths, the radian is a "pure number" that needs no unit symbol, and in mathematical writing the symbol "rad" is almost always omitted. In the absence of any symbol radians are assumed, and when degrees are meant the symbol ° is used.

How many meters in a radian?
Meter is a unit of length. Radian is a unit of angle. They don't relate.
What the difference between radians and degrees?
degree and radian are juest unit measurment of angle
What is the meaning of radian system?
The radian system describes angles in terms of the diameter of a unit circle, i.e. where the radius is 1. If two lines intersect at the radius of a unit circle, the angle in radians between those two lines is the length of the arc along the diameter of the circle delimited by those two lines. The diameter of a unit circle is 2 pi. In the degree system, the angle of one quarter of the circle is 90, while the radians of that same angle is pi / 2. One radian is approximately 57.3 degrees.
What is radian measure?
A unit of angular measure equal to the angle subtended at the center of a circle by an arc equal in length to the radius of the circle, approximately 57°17'44.6"
Is radian a fundamental unit?
No.
How many meters in a radian?
Meter is a unit of length. Radian is a unit of angle. They don't relate.
What is the unit to measure an angle called?
A radian.
Why you use radian?
it is used as an degree. It is an unit of angle.
How can the radian measure of an angle determine the arc length on the unit circle?
The radian measure IS the arc length of the unit circle, by definition - that is how the radian is defined in the first place.
Is angle is a derived quantity?
From the Wikipedia article about the radian: "The unit was formerly a SI supplementary unit, but this category was abolished in 1995 and the radian is now considered a SI derived unit." The radian can be derived as the ratio between two lengths. That makes it a dimensionless unit.
A unit for measuring an angle or an arc of a circle?
Radian = (180/pi)o
What is one radian?
It is the derived unit of plane angle and 1 radian = one full rotation/2π. Also, it is equal to 57.296°.
What is the SI unit of wind direction?
That would be an angle; the SI unit for angle is the radian. However, that is not the unit that is commonly used in this case.
What is angle and its unit?
Angle is the inclination between two lines or planes which have one one common point of contact and it's unit is degree or radian
What the difference between radians and degrees?
degree and radian are juest unit measurment of angle
What is a unit use to measure angles?
the unit used to measure angle is degree. It is also measured in radians.
Unit of measure of an angle?
Usually an angle is measured in degrees or radians.
