# angle units conversion

**Amount:** 1 quadrant (1/4 rev) of angle

**Equals:** 1.57 radians (rad) in angle

Converting **quadrant** to **radians** value in the angle units scale.

TOGGLE : from radians into quadrants in the other way around.

CONVERT : between other angle measuring units - complete list.

How many radians are in 1 quadrant? The answer is: 1 1/4 rev equals 1.57 rad

## 1.57 rad is converted to 1 of what?

The radians unit number 1.57 rad converts to 1 1/4 rev, one quadrant. **It is the EQUAL angle value of 1 quadrant but in the radians angle unit alternative.**

*radians (rad)*## Angles

This calculator is based on conversion of two angle units. An angle consists of two rays (as in sides of an angle sharing a common vertex or else called the endpoint.) Some belong to rotation measurements - spherical angles measured by arcs' lengths, pointing from the center, plus the radius. For a whole set of multiple units of angle on one page, try that Multiunit converter tool which has built in all angle unit-variations. Page with individual angle units.

# Converter type: angle units

First unit: quadrant (1/4 rev) is used for measuring angle.

Second: radian (rad) is unit of angle.

**QUESTION**:

15 1/4 rev = ? rad

**ANSWER**:

15 1/4 rev = 23.56 rad

Abbreviation, or prefix, for quadrant is:

**1/4 rev**

Abbreviation for radian is:

**rad**

## Other applications for this angle calculator ...

With the above mentioned two-units calculating service it provides, this angle converter proved to be useful also as a teaching tool:

1. in practicing quadrants and radians ( 1/4 rev vs. rad ) measures exchange.

2. for conversion factors between unit pairs.

3. work with angle's values and properties.
