Rumus Pemuaian

Muai panjang

Rumus:
$\!L_{t}=\!L_{0}(\!1+\alpha\times\Delta t)$

$\!L_{t}$ = panjang akhir (m, cm)
$\!L_{0}$ = panjang awal (m, cm)
$\alpha$ = koefisien muai panjang (/°C)
$\Delta t$ = perbedaan suhu (°C)

Muai volume

Rumus:
$\!V_{t}=\!V_{0}(\!1+\gamma\times\Delta\!t)$
Keterangan:

$\!V_{t}$ = volume akhir (m³, cm³)
$\!V_{0}$ = volume awal (m³, cm³)
$\gamma$ = $\!3\alpha$ = koefisien muai volume (/°C)
$\Delta t$ = selisih suhu (°C)

Muai luas

Rumus:
$\!A_{t}=\!A_{0}(\!1+\beta\times\Delta t)$
Keterangan:

$\!A_{t}$ = luas akhir (m², cm²)
$\!A_{0}$ = luas awal (m², cm²)
$\beta$ = $\!2\alpha$ = koefisien muai luas (/°C)
$\Delta t$ = selisih suhu (°C)
