# Convert inch / square second to mile / square hour

Learn how to convert 1 inch / square second to mile / square hour step by step.

## Calculation Breakdown

Set up the equation
$$1.0\left(\dfrac{inch}{square \text{ } second}\right)={\color{rgb(20,165,174)} x}\left(\dfrac{mile}{square \text{ } hour}\right)$$
Define the base values of the selected units in relation to the SI unit $$\left(\dfrac{meter}{square \text{ } second}\right)$$
$$\text{Left side: 1.0 } \left(\dfrac{inch}{square \text{ } second}\right) = {\color{rgb(89,182,91)} 2.54 \times 10^{-2}\left(\dfrac{meter}{square \text{ } second}\right)} = {\color{rgb(89,182,91)} 2.54 \times 10^{-2}\left(\dfrac{m}{s^{2}}\right)}$$
$$\text{Right side: 1.0 } \left(\dfrac{mile}{square \text{ } hour}\right) = {\color{rgb(125,164,120)} \dfrac{1609.344}{1.296 \times 10^{7}}\left(\dfrac{meter}{square \text{ } second}\right)} = {\color{rgb(125,164,120)} \dfrac{1609.344}{1.296 \times 10^{7}}\left(\dfrac{m}{s^{2}}\right)}$$
Insert known values into the conversion equation to determine $${\color{rgb(20,165,174)} x}$$
$$1.0\left(\dfrac{inch}{square \text{ } second}\right)={\color{rgb(20,165,174)} x}\left(\dfrac{mile}{square \text{ } hour}\right)$$
$$\text{Insert known values } =>$$
$$1.0 \times {\color{rgb(89,182,91)} 2.54 \times 10^{-2}} \times {\color{rgb(89,182,91)} \left(\dfrac{meter}{square \text{ } second}\right)} = {\color{rgb(20,165,174)} x} \times {\color{rgb(125,164,120)} {\color{rgb(125,164,120)} \dfrac{1609.344}{1.296 \times 10^{7}}}} \times {\color{rgb(125,164,120)} \left(\dfrac{meter}{square \text{ } second}\right)}$$
$$\text{Or}$$
$$1.0 \cdot {\color{rgb(89,182,91)} 2.54 \times 10^{-2}} \cdot {\color{rgb(89,182,91)} \left(\dfrac{m}{s^{2}}\right)} = {\color{rgb(20,165,174)} x} \cdot {\color{rgb(125,164,120)} \dfrac{1609.344}{1.296 \times 10^{7}}} \cdot {\color{rgb(125,164,120)} \left(\dfrac{m}{s^{2}}\right)}$$
$$\text{Cancel SI units}$$
$$1.0 \times {\color{rgb(89,182,91)} 2.54 \times 10^{-2}} \cdot {\color{rgb(89,182,91)} \cancel{\left(\dfrac{m}{s^{2}}\right)}} = {\color{rgb(20,165,174)} x} \times {\color{rgb(125,164,120)} \dfrac{1609.344}{1.296 \times 10^{7}}} \times {\color{rgb(125,164,120)} \cancel{\left(\dfrac{m}{s^{2}}\right)}}$$
$$\text{Conversion Equation}$$
$$2.54 \times 10^{-2} = {\color{rgb(20,165,174)} x} \times \dfrac{1609.344}{1.296 \times 10^{7}}$$
Switch sides
$${\color{rgb(20,165,174)} x} \times \dfrac{1609.344}{1.296 \times 10^{7}} = 2.54 \times 10^{-2}$$
Isolate $${\color{rgb(20,165,174)} x}$$
Multiply both sides by $$\left(\dfrac{1.296 \times 10^{7}}{1609.344}\right)$$
$${\color{rgb(20,165,174)} x} \times \dfrac{1609.344}{1.296 \times 10^{7}} \times \dfrac{1.296 \times 10^{7}}{1609.344} = 2.54 \times 10^{-2} \times \dfrac{1.296 \times 10^{7}}{1609.344}$$
$$\text{Cancel}$$
$${\color{rgb(20,165,174)} x} \times \dfrac{{\color{rgb(255,204,153)} \cancel{1609.344}} \times {\color{rgb(99,194,222)} \cancel{1.296}} \times {\color{rgb(166,218,227)} \cancel{10^{7}}}}{{\color{rgb(99,194,222)} \cancel{1.296}} \times {\color{rgb(166,218,227)} \cancel{10^{7}}} \times {\color{rgb(255,204,153)} \cancel{1609.344}}} = 2.54 \times {\color{rgb(255,204,153)} \cancel{10^{-2}}} \times \dfrac{1.296 \times {\color{rgb(255,204,153)} \cancelto{10^{5}}{10^{7}}}}{1609.344}$$
$$\text{Simplify}$$
$${\color{rgb(20,165,174)} x} = \dfrac{2.54 \times 1.296 \times 10^{5}}{1609.344}$$
Solve $${\color{rgb(20,165,174)} x}$$
$${\color{rgb(20,165,174)} x}\approx204.54545455\approx2.0455 \times 10^{2}$$
$$\text{Conversion Equation}$$
$$1.0\left(\dfrac{inch}{square \text{ } second}\right)\approx{\color{rgb(20,165,174)} 2.0455 \times 10^{2}}\left(\dfrac{mile}{square \text{ } hour}\right)$$
