As we know One yd/s² is equal to 914.4 mm/s² (1 yd/s² = 914.4 mm/s²).

To convert Yard/square second to Millimeter/square second, multiply your yd/s² figure by 914.4.

Example : convert 25 yd/s² to mm/s²:

25 yd/s² = 25 × 914.4 mm/s² = mm/s²

To convert Millimeter/square second to Yard/square second, divide your mm/s² figure by 914.4.

Example : convert 25 mm/s² to yd/s²:

25 mm/s² = 25 ÷ 914.4 yd/s² = yd/s²
