Convert Square inches per second to Square centimetres per second
Convert Square inches per second (in²/s) to Square centimetres per second (cm²/s) instantly and accurately.
Conversion Formula
cm²/s = in²/s × 6.4516
About Square inches per second
The square inch per second (in²/s) equals 0.0254² = 6.4516 × 10⁻⁴ m²/s. It is the coherent FPS kinematic unit based on the inch, found in US fluid power, hydraulics, and bearing-design references. 1 in²/s = 645.16 cSt = 6.4516 St.
About Square centimetres per second
The square centimetre per second (cm²/s) equals 10⁻⁴ m²/s, numerically identical to 1 stoke (St). It is the explicit CGS dimensional form, preferred in dimensional analysis or when avoiding named units. 1 cm²/s = 1 St = 100 cSt.
