Convert the following degree measure to radian measure.
\[
60^{\circ}
\]

Step 1 ：Understand the problem: We are asked to convert a degree measure to a radian measure.

Step 2 ：Recall the conversion factor: We know that \(\pi\) radians is equal to 180 degrees.

Step 3 ：Set up the conversion: We can set up the conversion as follows: \(60\) degrees * \((\pi\) radians / 180 degrees)

Step 4 ：Perform the calculation: The degrees cancel out, leaving us with: \(60 * \pi / 180 = \pi/3\) radians

Step 5 ：Simplify the result: The result is already in its simplest form.

Step 6 ：Check the result: The result is a radian measure, as required by the problem.

Step 7 ：\(\boxed{\pi/3}\) radians is the final answer.
