How Cubic Interplanar Spacing works
Calculate dₕₖₗ=a/√(h²+k²+l²) for a cubic crystal. Miller indices cannot all be zero; lattice parameter and output share the same length unit. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.1
- Interplanar Spacing
- The resulting interplanar spacing returned as a number.
Limitations and assumptions
- Crystallographic calculations assume the stated ideal lattice, indexing, wavelength, occupancy, and unit-cell geometry. Defects, strain, texture, thermal expansion, mixed phases, and instrumental corrections are outside the compact model.
- Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.
Alternative or Complementary approaches
Check units and significant figures, compare the result with limiting cases, and use measured or source-specific constants where available. Laboratory, safety, and regulatory decisions require validated methods and appropriate uncertainty analysis.

- Cubic Lattice Parameter from Density
Calculate the cubic unit-cell edge from Z formula units per cell, molar mass, and density: a³=ZM/(ρNₐ). Enter SI molar mass (kg/mol) and density (kg/m³); output is metres.
- Analytical Spike Recovery
Calculate percent recovery as (measured spiked result − unspiked result)/known spike amount ×100. All three quantities must use the same unit; values outside 0–100% can reveal matrix effects or measurement problems.
- Analytical Relative Standard Deviation
Calculate relative standard deviation from a supplied sample standard deviation and mean: RSD%=100s/|mean|. The mean cannot be zero; this is a precision measure, not an accuracy estimate.
