## Thermal Expansion of Liquids Formula

 $$\large{ \Delta V = a_v \; V_i \; \Delta T }$$ (volumetric or cubical expansion)

### Where:

 Units English Metric $$\large{ \Delta V }$$ = volume differential $$\large{in^3}$$ $$\large{mm^3}$$ $$\large{ \Delta T }$$ = temperature differential $$\large{F}$$ $$\large{C}$$ $$\large{ V_i }$$ = initial volume of object $$\large{in^3}$$ $$\large{mm^3}$$ $$\large{ a_v }$$ = volumetric thermal expansion coefficient $$\large{ \frac{in^3}{in^3\;F} }$$ $$\large{ \frac{mm^3}{mm^3\;C} }$$
