Metre

The SI unit of displacement is the metre.

\(\ds \) \(\) \(\ds 1\) metre
\(\ds \) \(=\) \(\ds 100\) centimetres
\(\ds \) \(=\) \(\ds 1000\) millimetres
\(\ds \) \(=\) \(\ds 1 \, 000 \, 000\) micrometres
\(\ds \) \(=\) \(\ds 39 \cdotp 3708\) inches
\(\ds \) \(=\) \(\ds 3 \cdotp 28\) feet
\(\ds \) \(=\) \(\ds 1 \cdotp 09\) yards


Centimetre

The CGS unit of displacement is the centimetre $\mathrm {cm}$.

\(\ds \) \(\) \(\ds 1\) centimetre
\(\ds \) \(=\) \(\ds 10\) millimetres
\(\ds \) \(=\) \(\ds 10 \, 000\) micrometres
\(\ds \) \(=\) \(\ds 0 \cdotp 01\) metre
\(\ds \) \(=\) \(\ds 0 \cdotp 39370 \, 8\) inch
\(\ds \) \(=\) \(\ds 0 \cdotp 0328\) foot
\(\ds \) \(=\) \(\ds 0 \cdotp 0109\) yard


Foot

The FPS unit of displacement is the foot.

\(\ds \) \(\) \(\ds 1\) foot
\(\ds \) \(=\) \(\ds 12\) inches
\(\ds \) \(=\) \(\ds \dfrac 1 3\) yard
\(\ds \) \(=\) \(\ds 30 \cdotp 48\) centimetres \(\quad\) (exact)
\(\ds \) \(=\) \(\ds 0 \cdotp 3048\) metres \(\quad\) (exact)
