Convert Square Feet per Second to Square Meters per Second

Formula

m²/s = ft²/s × 0.09290304

or m²/s = ft²/s ÷ 10.76391041671

Derivation from SI units:

• 1 ft²/s = 0.09290304 m²/s (exact)
• 1 m²/s = 1 m² ÷ 1 s

Both units are defined exactly, so the factor is exact. Square Foot per Second definition: square foot per second; Square Meter per Second definition: square meter per second.

Worked examples

1. Water at 68 °F, about 0.0000108 ft²/s, is 0.000001003352832 m²/s.
   0.0000108 ft²/s × 0.09290304 = 0.000001003352832 m²/s
2. Air at 68 °F, about 0.000164 ft²/s, is 0.00001523609856 m²/s.
   0.000164 ft²/s × 0.09290304 = 0.00001523609856 m²/s

Where it's used

US kinematic viscosities in ft²/s are converted to m²/s for SI software and Reynolds-number checks. Multiply by 0.09290304.
