m/m/K (Meter/Meter/Kelvin)
Definition: The SI unit for the coefficient of linear thermal expansion. It represents the fractional change in length (meter per meter) per degree Kelvin change in temperature.
History/origin: Established as part of the International System of Units to provide a universal scientific standard for material science and thermodynamics.
Current use: Used globally in scientific research, materials engineering, and high-level structural calculations.
mm/m/°C (Millimeter/Meter/°C)
Definition: A metric unit showing millimeters of expansion per meter of material per degree Celsius.
History/origin: Commonly used in civil engineering where expansion is measured in more "visible" units like millimeters over long structures like bridges.
Current use: Frequently used in building codes and infrastructure design manuals to specify joint gaps.

How to Convert m/m/K (Meter/Meter/Kelvin) to mm/m/°C (Millimeter/Meter/°C)
1 m_m_k = 0.001 mm_m_c
1 mm_m_c = 1000 m_m_k
Example: convert 15 m_m_k to mm_m_c:
15 m_m_k = 15 × 0.001 mm_m_c = 0.015 mm_m_c
