Metric and Imperial Units

The above formulas may be used with both imperial and metric units. As with all calculations care must be taken to keep consistent units throughout with examples of units which should be adopted listed below:

Notation

• V = volume, in⁴ or mm⁴
• V_F = final volume, in⁴ or mm⁴
• ∆_T = change in temperature, ᵒK or ᵒC
• ∆_V = change in volume, in⁴ or mm⁴
• α = coefficient of thermal expansion, ᵒK^-1 or ᵒC^-1
