Convert arc second to revolution

Learn how to convert 1 arc second to revolution step by step.

Calculation Breakdown

Set up the equation
\(1.0\left(arc \text{ } second\right)={\color{rgb(20,165,174)} x}\left(revolution\right)\)
Define the base values of the selected units in relation to the SI unit \(\left(radian\right)\)
\(\text{Left side: 1.0 } \left(arc \text{ } second\right) = {\color{rgb(89,182,91)} \dfrac{π}{6.48 \times 10^{5}}\left(radian\right)} = {\color{rgb(89,182,91)} \dfrac{π}{6.48 \times 10^{5}}\left(rad\right)}\)
\(\text{Right side: 1.0 } \left(revolution\right) = {\color{rgb(125,164,120)} 2.0 \times π\left(radian\right)} = {\color{rgb(125,164,120)} 2.0 \times π\left(rad\right)}\)
Insert known values into the conversion equation to determine \({\color{rgb(20,165,174)} x}\)
\(1.0\left(arc \text{ } second\right)={\color{rgb(20,165,174)} x}\left(revolution\right)\)
\(\text{Insert known values } =>\)
\(1.0 \times {\color{rgb(89,182,91)} \dfrac{π}{6.48 \times 10^{5}}} \times {\color{rgb(89,182,91)} \left(radian\right)} = {\color{rgb(20,165,174)} x} \times {\color{rgb(125,164,120)} {\color{rgb(125,164,120)} 2.0 \times π}} \times {\color{rgb(125,164,120)} \left(radian\right)}\)
\(1.0 \cdot {\color{rgb(89,182,91)} \dfrac{π}{6.48 \times 10^{5}}} \cdot {\color{rgb(89,182,91)} \left(rad\right)} = {\color{rgb(20,165,174)} x} \cdot {\color{rgb(125,164,120)} 2.0 \times π} \cdot {\color{rgb(125,164,120)} \left(rad\right)}\)
\(\text{Cancel SI units}\)
\(1.0 \times {\color{rgb(89,182,91)} \dfrac{π}{6.48 \times 10^{5}}} \cdot {\color{rgb(89,182,91)} \cancel{\left(rad\right)}} = {\color{rgb(20,165,174)} x} \times {\color{rgb(125,164,120)} 2.0 \times π} \times {\color{rgb(125,164,120)} \cancel{\left(rad\right)}}\)
\(\text{Conversion Equation}\)
\(\dfrac{π}{6.48 \times 10^{5}} = {\color{rgb(20,165,174)} x} \times 2.0 \times π\)
Cancel factors on both sides
\(\text{Cancel factors}\)
\(\dfrac{{\color{rgb(255,204,153)} \cancel{π}}}{6.48 \times 10^{5}} = {\color{rgb(20,165,174)} x} \times {\color{rgb(255,204,153)} \cancel{π}} \times 2.0\)
\(\dfrac{1.0}{6.48 \times 10^{5}} = {\color{rgb(20,165,174)} x} \times 2.0\)
Switch sides
\({\color{rgb(20,165,174)} x} \times 2.0 = \dfrac{1.0}{6.48 \times 10^{5}}\)
Isolate \({\color{rgb(20,165,174)} x}\)
Multiply both sides by \(\left(\dfrac{1.0}{2.0}\right)\)
\({\color{rgb(20,165,174)} x} \times 2.0 \times \dfrac{1.0}{2.0} = \dfrac{1.0}{6.48 \times 10^{5}} \times \dfrac{1.0}{2.0}\)
\({\color{rgb(20,165,174)} x} \times {\color{rgb(255,204,153)} \cancel{2.0}} \times \dfrac{1.0}{{\color{rgb(255,204,153)} \cancel{2.0}}} = \dfrac{1.0 \times 1.0}{6.48 \times 10^{5} \times 2.0}\)
\({\color{rgb(20,165,174)} x} = \dfrac{1.0}{6.48 \times 10^{5} \times 2.0}\)
Rewrite equation
\(\dfrac{1.0}{10^{5}}\text{ can be rewritten to }10^{-5}\)
\({\color{rgb(20,165,174)} x} = \dfrac{10^{-5}}{6.48 \times 2.0}\)
Solve \({\color{rgb(20,165,174)} x}\)
\({\color{rgb(20,165,174)} x}\approx0.0000007716\approx7.716 \times 10^{-7}\)
\(\text{Conversion Equation}\)
\(1.0\left(arc \text{ } second\right)\approx{\color{rgb(20,165,174)} 7.716 \times 10^{-7}}\left(revolution\right)\)
