Thermal expansion calculator

Calculate length change and final length with your own figures.

Your numbers

Use the units shown. Results update as you change valid inputs.

Use length change and final length to compare changes to your inputs. The method and limits below explain the scope.

Examples

Examples

Try the starting example

Initial length (m)
1
Expansion coefficient (1/K)
1.2e-05
Temperature change (K)
100
Length change (m)
0.0012
Final length (m)
1.0012

Try another scenario

Initial length (m)
1.1
Expansion coefficient (1/K)
1.2e-05
Temperature change (K)
100
Length change (m)
0.00132
Final length (m)
1.10132
Calculation method

Calculation method

Length change (m)

a × b × c

Final length (m)

a × (1+b × c)

Symbols and units
a
Initial length (m)
b
Expansion coefficient (1/K)
c
Temperature change (K)

Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.

Assumptions & limits

Assumptions & limits

  • Linear thermal expansion with a constant coefficient and no mechanical constraint.
