yd/s vers ft/s convertisseur - Yard par Seconde vers Pied par Seconde

Conversion derivation

Express both yd/s and ft/s in the same base unit m/s (meter per second), then cancel the shared base unit.

1. 1

   Rewrite yd/s in the base unit

   $$1yd/s=0.9144m/s$$
2. 2

   Rewrite ft/s in the base unit

   $$1ft/s=0.3048m/s$$
3. 3

   Forward conversion

   $$\begin{array}{rl}1yd/s& =\frac{0.9144\cancel{m/s}}{0.3048\cancel{m/s}}\times 1ft/s\\ & =\frac{0.9144}{0.3048}ft/s\\ & =3ft/s\end{array}$$
4. 4

   Reverse conversion

   $$\begin{array}{rl}1ft/s& =\frac{0.3048\cancel{m/s}}{0.9144\cancel{m/s}}\times 1yd/s\\ & =\frac{0.3048}{0.9144}yd/s\\ & =0.333333333333yd/s\end{array}$$
