How to convert Square foot to Square inch
$$\text{Area}_{\text{in²}} = \text{Area}_{\text{ft²}} \cdot 144$$
Examples
Example 1
Convert $30.0\ \text{ft²}$ to $\text{in²}$.
$$\text{Area}_{\text{in²}} = 30.0 \cdot 144$$
$$\text{Area}_{\text{in²}} = 4320$$
$$\therefore \ 30.0\ \text{ft²} = 4320 \ \text{in²}$$
Example 2
Convert $75.0\ \text{ft²}$ to $\text{in²}$.
$$\text{Area}_{\text{in²}} = 75.0 \cdot 144$$
$$\text{Area}_{\text{in²}} = 10800$$
$$\therefore \ 75.0\ \text{ft²} = 10800 \ \text{in²}$$
Example 3
Convert $110.0\ \text{ft²}$ to $\text{in²}$.
$$\text{Area}_{\text{in²}} = 110.0 \cdot 144$$
$$\text{Area}_{\text{in²}} = 15840$$
$$\therefore \ 110.0\ \text{ft²} = 15840 \ \text{in²}$$
Example 4
Convert $145.0\ \text{ft²}$ to $\text{in²}$.
$$\text{Area}_{\text{in²}} = 145.0 \cdot 144$$
$$\text{Area}_{\text{in²}} = 20880$$
$$\therefore \ 145.0\ \text{ft²} = 20880 \ \text{in²}$$
Example 5
Convert $180.0\ \text{ft²}$ to $\text{in²}$.
$$\text{Area}_{\text{in²}} = 180.0 \cdot 144$$
$$\text{Area}_{\text{in²}} = 25920$$
$$\therefore \ 180.0\ \text{ft²} = 25920 \ \text{in²}$$
