Area
Convert square inch (in²) to square foot (ft²). Area sets heat-transfer surface, flow cross-sections, and footprints, in m² or ft².
1 in² = 0.006944444 ft²
To convert square inch to square foot, multiply the in² value by 0.006944444. To go the other way, divide by 0.006944444 (or multiply by 144).
| in² | ft² |
|---|---|
| 1 | 0.006944444 |
| 2 | 0.01388889 |
| 5 | 0.03472222 |
| 10 | 0.06944444 |
| 25 | 0.1736111 |

| 100 | 0.6944444 |
| 250 | 1.736111 |
| 500 | 3.472222 |
| 1000 | 6.944444 |
Exchanger surface is quoted in m² or ft²; orifice and nozzle areas in mm² or in².
Flow area scales with the square of diameter, so doubling a pipe's bore quadruples its area.
Worked example. A area of 15500.03 in² is 107.6391 ft².
Multiply the value in in² by 0.006944444 to get ft². For example, 10 in² = 0.06944444 ft².
1 in² equals 0.006944444 ft².
Exchanger surface is quoted in m² or ft²; orifice and nozzle areas in mm² or in².
