 angle (required):
The angle value in degrees that you want to convert to radians. Must be a number or a reference to a cell containing a number.
Examples
Here are a few example use cases that explain how to use theRADIANS
formula in Google Sheets.
Converting degrees to radians
If you have an angle value in degrees that you need to use in a mathematical calculation that requires radians, you can use the RADIANS
formula to convert it to radians.
Trigonometric calculations
Trigonometric functions such as sine, cosine, and tangent require angle values to be in radians. You can use the RADIANS
formula to convert an angle value from degrees to radians before using it in a trigonometric calculation.
Common Mistakes
RADIANS
not working? Here are some common mistakes people make when using the RADIANS
Google Sheets Formula:
Missing angle argument
One of the most common mistakes is forgetting to include the angle argument in the RADIANS formula. This will result in an error or an incorrect calculation. Double check that you have included the angle argument in the correct format.
Incorrect unit of measurement
Another common mistake is using the wrong unit of measurement for the angle argument. RADIANS requires the angle to be in radians, not degrees or other units. Make sure you convert your angle to radians before using it in the formula.
Incorrect syntax
If you receive an error message, it may be due to incorrect syntax. Double check that you have entered the formula correctly, including the correct spelling and punctuation. Make sure you have included the angle argument and that it is in the correct format.
Related Formulas
The following functions are similar to RADIANS
or are often used with it in a formula:

DEGREES
The
DEGREES
function converts an angle value in radians to degrees. This is useful when working with trigonometric functions that require angles in degrees. The function takes one parameter,angle
, which is the angle value in radians. 
SIN
The
SIN
function in Google Sheets returns the sine of a given angle in radians. Sine is a mathematical function that describes a smooth repetitive oscillation. It is commonly used in trigonometry, physics, and engineering to model phenomena such as waves, oscillations, and periodic motion. 
COS
The
COS
function in Google Sheets returns the cosine of an angle provided in radians. It is commonly used in trigonometry to calculate the cosine of an angle. The function takes one parameter, the angle in radians. 
TAN
The
TAN
function returns the tangent of an angle specified in radians. Tangent is the ratio of the length of the opposite side to the length of the adjacent side of a rightangled triangle. This function is commonly used in trigonometry and geometry calculations.
