Mining and geology education · Sample calculations
Sample grade by mass
Calculate contained material as a mass percentage of a user-supplied sample mass.
Method and scope
Mass grade = contained material mass ÷ total sample mass × 100%.
Calculate a simple sample mass fraction for learning or to summarize a provided assay result. Intended for Learners, General geology use.
Inputs- Contained material mass — kg, g, t
- Total sample mass — kg, g, t
SOURCE AND LIMITS
Assumptions: Contained material mass and sample mass refer to the same representative sample. Both mass values use compatible units.
Limitations: Representativeness, sampling bias, assay uncertainty, and mineral processing are not assessed.
Method version 1.0.0 · Unit registry and result provenance are shown after calculation. This tool is limited to the documented scope.Explore related fields
