ft から yd 変換ツール - フィート から ヤード

Conversion derivation

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

1. 1

   Rewrite ft in the base unit

   $$1\mathrm{ft}=0.3048\mathrm{m}$$
2. 2

   Rewrite yd in the base unit

   $$1\mathrm{yd}=0.9144\mathrm{m}$$
3. 3

   Forward conversion

   $$\begin{array}{rl}1\mathrm{ft}& =\frac{0.3048\cancel{\mathrm{m}}}{0.9144\cancel{\mathrm{m}}}\times 1\mathrm{yd}\\ & =\frac{0.3048}{0.9144}\mathrm{yd}\\ & =0.333333333333\mathrm{yd}\end{array}$$
4. 4

   Reverse conversion

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