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

• A = area, in⁴ or mm⁴
• A_F = final area, in⁴ or mm⁴
• ∆_A = change in area, in⁴ or mm⁴
• ∆_T = change in temperature, ᵒK or ᵒC
• α = coefficient of thermal expansion, ᵒK^-1 or ᵒC^-1
