To convert degrees to radians, you need to multiply the degree measurement by the conversion factor π/180.
Let's convert 1/3 degree to radians:
1/3 degree * (π/180 radians/degree)
To simplify the expression, we can multiply the numerator and denominator by π:
(1/3) * (π/180) * (π/π) = π/540 radians
Therefore, 1/3 degree is equal to π/540 radians.
