Accuracy & Precision Measurement and Standardization

Introduction

In early America, some measures and measuring instruments did not exist, while those that existed were irregular and not accepted by all parties, which resulted in much confusion, argument, and wasted effort.   Eventual standardization of various measures and their instruments contributed significantly to improved productivity, efficiency, and general living standards.   Measurements, precision and standards are grouped by (1) length, area, and volume, (2) time, and (3) physical and chemical.
