Area
Convert square foot (ft²) to square millimetre (mm²). Area sets heat-transfer surface, flow cross-sections, and footprints, in m² or ft².
1 ft² = 92903.04 mm²
To convert square foot to square millimetre, multiply the ft² value by 92903.04. To go the other way, divide by 92903.04 (or multiply by 1.0764e-5).
| ft² | mm² |
|---|---|
| 1 | 92903.04 |
| 2 | 185806.1 |
| 5 | 464515.2 |
| 10 | 929030.4 |
| 25 | 2322576 |
| 50 | 4645152 |
| 100 | 9290304 |
| 250 | 2.3226e+7 |
| 500 | 4.6452e+7 |
| 1000 | 9.2903e+7 |
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 107.6391 ft² is 1e+7 mm².
Multiply the value in ft² by 92903.04 to get mm². For example, 10 ft² = 929030.4 mm².
1 ft² equals 92903.04 mm².
Exchanger surface is quoted in m² or ft²; orifice and nozzle areas in mm² or in².
