Area
Convert square millimetre (mm²) to square inch (in²). Area sets heat-transfer surface, flow cross-sections, and footprints, in m² or ft².
1 mm² = 0.001550003 in²
To convert square millimetre to square inch, multiply the mm² value by 0.001550003. To go the other way, divide by 0.001550003 (or multiply by 645.16).
| mm² | in² |
|---|---|
| 1 | 0.001550003 |
| 2 | 0.003100006 |
| 5 | 0.007750016 |
| 10 | 0.01550003 |
| 25 | 0.03875008 |
| 50 | 0.07750016 |
| 100 | 0.1550003 |
| 250 | 0.3875008 |
| 500 | 0.7750016 |
| 1000 | 1.550003 |
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 1e+7 mm² is 15500.03 in².
Multiply the value in mm² by 0.001550003 to get in². For example, 10 mm² = 0.01550003 in².
1 mm² equals 0.001550003 in².
Exchanger surface is quoted in m² or ft²; orifice and nozzle areas in mm² or in².
