The Arc Length of a Parabola calculator computes the arc length of a parabola based on the distance (a) from the apex of the parabola along the axis to a point, and the width (b) of the parabola at that point perpendicular to the axis.
INSTRUCTIONS: Choose units and enter the following:
Arc Length (L): The calculator returns the length in meters. However, this can be automatically converted to other length units via the pull-down menu.
`L = 1/2 sqrt(b^2 + 16*a^2) + b^2/(8*a) ln((4*a+sqrt(b^2+16*a^2))/b)`
