French Normalization - Nosometric System of Units

This official AFNOR standard document UNM 00-001 from January 2002 establishes the fundamental rules and terminology for the nosometric system of units, a whimsical measurement framework based on subjective human perception and estimation. The document outlines the principles governing pifometry, the science of measuring intangible and personal quantities that vary by individual and context. It defines three core principles: pifometers are strictly personal and non-transferable, contrary pifometric expressions do not cancel each other, and averaging pifometric values yields no useful information. The standard comprehensively catalogs quantity units including palanquée, tapée, flopée, and triplotée, value units such as tripette and roupie de sansonnet, and specialized units for destination, adjustment, length, distance, time, speed, temperature, maritime measurements, and diverse applications. Each unit entry includes definitions, examples of usage, and practical guidance for interpretation. The document emphasizes pifometry's ancient and universal nature across cultures and its distinction from conventional measurement systems.
