Formula

Formula
in²/s = m²/s × 1550.003

Multiply any value in square metres per second by 1550.003 to obtain the value in square inches per second.

Worked example

Convert 1 m²/s to in²/s.

  1. 01Start with 1 m²/s.
  2. 02Multiply by the conversion factor: 1 × 1550.003 = 1550 in²/s.
Result1 m²/s = 1550 in²/s

FAQ

What is the conversion factor from m²/s to in²/s?
1 m²/s equals 1550.003 in²/s. To convert, multiply the value in square metres per second by 1550.003.
How do I convert 1 m²/s to in²/s?
1 m²/s = 1550 in²/s. For any value, multiply by 1550.003.
How do I convert in²/s back to m²/s?
Divide by the same factor — or equivalently, multiply by 0.00064516. So 1 in²/s = 0.00064516 m²/s.
When would I need to convert square metre per second to square inch per second?
Kinematic viscosity conversions between m²/s and in²/s arise in hydraulic fluid selection, lubricant grading (ISO VG), pipe flow Reynolds number calculations, and fuel-oil specification. Kinematic viscosity equals dynamic viscosity divided by fluid density and cannot be directly compared to dynamic viscosity without that context.
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
