Standard Measures are set in law as benchmarks for distance, weights, and volumes. The measures were considered permanent and static, an unchanging reference for public use. Disputes and deviations were arbitrated in accordance with the Weights and Measures Acts. However the reference objects decay, get damaged. Standards require maintenance, duplication or revision.
Katya Robin designed a revised set of Standard Measures based on the 1NCH. This is an invented unit of measure based on an Imperial inch but made in metric.
Standard Measures has been exhibited variously at: 12x12x12, FAB, Fabricate.
