Interpretation
Applications & Usage Interpretation
For applications and usage, the NLGI grade directly maps grease consistency to measurable penetration, with NLGI 2 at 265–295 and NLGI 000 at 445–475 in tenths of a millimeter, meaning higher grades are firmer and better suited to tighter application needs.
