The RADIANS function in Excel is a simple yet powerful tool that facilitates the conversion of angle measurements from degrees into radians. This is particularly useful in various mathematical calculations, including trigonometry, where radians are often the preferred unit of measurement.

Syntax

RADIANS(angle)

• angle: The angle in degrees that you wish to convert into radians.

Example #1

=RADIANS(180)

This function converts 180 degrees to radians, resulting in 3.14159 (approximately).

Example #2

=RADIANS(90)

This function converts 90 degrees to radians, yielding a result of 1.5708 (approximately).

Example #3

=RADIANS(45)

This function converts 45 degrees to radians, producing a result of 0.7854 (approximately).

Error handling

• VALUE!: This error occurs when the input for the angle parameter is a non-numeric value.
• NUM!: Although seldom encountered with this function, if a number exceeds the allowed range of the angle input, this error may present itself.

Conclusion

In summary, the RADIANS function is an essential tool within Excel for anyone needing to convert degrees to radians efficiently. Its straightforward syntax and ease of use make it a valuable asset in mathematical and scientific calculations, allowing users to seamlessly integrate angle conversions into their spreadsheets.
