Square Inch to Square Kilometer Conversion Formula

To convert from Square Inch (in2) to Square Kilometer (km2), use the following formula:

 Square Kilometer (km2)\textbf{ Square Kilometer } (km^{2})

=1144×110.7639×1106× Square Inch (in2)= \frac{1}{144} \times \frac{1}{10.7639} \times \frac{1}{10^{6}}\times \textbf{ Square Inch } (in^{2})

=6.4516062435032325128×10−10× Square Inch (in2)= 6.4516062435032325128\times 10^{-10}\times \textbf{ Square Inch } (in^{2})

With 110.7639\frac{1}{10.7639} is the ratio between the base units Square Meter (m2) and Square Foot (ft2).

Example

Let's convert 5 Square Inch (in2) to Square Kilometer (km2).

Using the formula:

5×6.4516062435032325128×10−10=3.2258031217516162564×10−95 \times 6.4516062435032325128\times 10^{-10} = 3.2258031217516162564\times 10^{-9}

Therefore, 5 Square Inch (in2) is equal to 3.2258031217516162564×10−93.2258031217516162564\times 10^{-9} Square Kilometer (km2).
