# Convert degree / hour to radian / hour

Learn how to convert 1 degree / hour to radian / hour step by step.

## Calculation Breakdown

Set up the equation
$$1.0\left(\dfrac{degree}{hour}\right)={\color{rgb(20,165,174)} x}\left(\dfrac{radian}{hour}\right)$$
Define the base values of the selected units in relation to the SI unit $$\left(\dfrac{radian}{second}\right)$$
$$\text{Left side: 1.0 } \left(\dfrac{degree}{hour}\right) = {\color{rgb(89,182,91)} \dfrac{π}{6.48 \times 10^{5}}\left(\dfrac{radian}{second}\right)} = {\color{rgb(89,182,91)} \dfrac{π}{6.48 \times 10^{5}}\left(\dfrac{rad}{s}\right)}$$
$$\text{Right side: 1.0 } \left(\dfrac{radian}{hour}\right) = {\color{rgb(125,164,120)} \dfrac{1.0}{3.6 \times 10^{3}}\left(\dfrac{radian}{second}\right)} = {\color{rgb(125,164,120)} \dfrac{1.0}{3.6 \times 10^{3}}\left(\dfrac{rad}{s}\right)}$$
Insert known values into the conversion equation to determine $${\color{rgb(20,165,174)} x}$$
$$1.0\left(\dfrac{degree}{hour}\right)={\color{rgb(20,165,174)} x}\left(\dfrac{radian}{hour}\right)$$
$$\text{Insert known values } =>$$
$$1.0 \times {\color{rgb(89,182,91)} \dfrac{π}{6.48 \times 10^{5}}} \times {\color{rgb(89,182,91)} \left(\dfrac{radian}{second}\right)} = {\color{rgb(20,165,174)} x} \times {\color{rgb(125,164,120)} {\color{rgb(125,164,120)} \dfrac{1.0}{3.6 \times 10^{3}}}} \times {\color{rgb(125,164,120)} \left(\dfrac{radian}{second}\right)}$$
$$\text{Or}$$
$$1.0 \cdot {\color{rgb(89,182,91)} \dfrac{π}{6.48 \times 10^{5}}} \cdot {\color{rgb(89,182,91)} \left(\dfrac{rad}{s}\right)} = {\color{rgb(20,165,174)} x} \cdot {\color{rgb(125,164,120)} \dfrac{1.0}{3.6 \times 10^{3}}} \cdot {\color{rgb(125,164,120)} \left(\dfrac{rad}{s}\right)}$$
$$\text{Cancel SI units}$$
$$1.0 \times {\color{rgb(89,182,91)} \dfrac{π}{6.48 \times 10^{5}}} \cdot {\color{rgb(89,182,91)} \cancel{\left(\dfrac{rad}{s}\right)}} = {\color{rgb(20,165,174)} x} \times {\color{rgb(125,164,120)} \dfrac{1.0}{3.6 \times 10^{3}}} \times {\color{rgb(125,164,120)} \cancel{\left(\dfrac{rad}{s}\right)}}$$
$$\text{Conversion Equation}$$
$$\dfrac{π}{6.48 \times 10^{5}} = {\color{rgb(20,165,174)} x} \times \dfrac{1.0}{3.6 \times 10^{3}}$$
Cancel factors on both sides
$$\text{Cancel factors}$$
$$\dfrac{π}{6.48 \times {\color{rgb(255,204,153)} \cancelto{10^{2}}{10^{5}}}} = {\color{rgb(20,165,174)} x} \times \dfrac{1.0}{3.6 \times {\color{rgb(255,204,153)} \cancel{10^{3}}}}$$
$$\text{Simplify}$$
$$\dfrac{π}{6.48 \times 10^{2}} = {\color{rgb(20,165,174)} x} \times \dfrac{1.0}{3.6}$$
Switch sides
$${\color{rgb(20,165,174)} x} \times \dfrac{1.0}{3.6} = \dfrac{π}{6.48 \times 10^{2}}$$
Isolate $${\color{rgb(20,165,174)} x}$$
Multiply both sides by $$\left(\dfrac{3.6}{1.0}\right)$$
$${\color{rgb(20,165,174)} x} \times \dfrac{1.0}{3.6} \times \dfrac{3.6}{1.0} = \dfrac{π}{6.48 \times 10^{2}} \times \dfrac{3.6}{1.0}$$
$$\text{Cancel}$$
$${\color{rgb(20,165,174)} x} \times \dfrac{{\color{rgb(255,204,153)} \cancel{1.0}} \times {\color{rgb(99,194,222)} \cancel{3.6}}}{{\color{rgb(99,194,222)} \cancel{3.6}} \times {\color{rgb(255,204,153)} \cancel{1.0}}} = \dfrac{π \times 3.6}{6.48 \times 10^{2} \times 1.0}$$
$$\text{Simplify}$$
$${\color{rgb(20,165,174)} x} = \dfrac{π \times 3.6}{6.48 \times 10^{2}}$$
Rewrite equation
$$\dfrac{1.0}{10^{2}}\text{ can be rewritten to }10^{-2}$$
$$\text{Rewrite}$$
$${\color{rgb(20,165,174)} x} = \dfrac{10^{-2} \times π \times 3.6}{6.48}$$
Solve $${\color{rgb(20,165,174)} x}$$
$${\color{rgb(20,165,174)} x}\approx0.0174532925\approx1.7453 \times 10^{-2}$$
$$\text{Conversion Equation}$$
$$1.0\left(\dfrac{degree}{hour}\right)\approx{\color{rgb(20,165,174)} 1.7453 \times 10^{-2}}\left(\dfrac{radian}{hour}\right)$$
