About this radiation length converter
Convert radiation length between areal mass units and material-dependent length units for particle physics, detector design, accelerator work, and shielding estimates.
Areal mass units such as g/cm2 are material-independent. Length units such as cm, m, inches, and mm depend on the selected material density.
Units covered
Areal mass
g/cm2, kg/m2, mg/cm2, ug/cm2, g/m2, lb/ft2, and oz/in2.
Length units
cm, m, inches, and mm using selected material density.
Materials
Lead, carbon, aluminum, iron, copper, water, concrete, air, and a 1 g/cm3 custom reference.
How to use it
- Select the material when either unit is a physical length.
- Enter the radiation length value and choose source and target units.
- Use areal mass units when comparing materials independent of density.
