Rhaetic units
The Rhaetic system of units (Ladin: Liviei dla Raetia; literally Rhaetic standards), is the system of units defined first by the Royal Trading Standards Decree 1716 and has been developed since through a number of amendments and specifications.
The Rhaetic system developed from earlier measures of cultural significance in Tirol, prior to the Trading Standards Decree, each area of Tirol defined its own standards, standardised by duchy in some areas, whilst differing from city to city in others.
Following the Tiroler Civil War many of the Rhaetic units were replaced by the metric system in most areas. Remnants of the Rhaetic system are preserved in some areas, including historic signage and "league-stones" on major highways that mark the number of Rhaetic leagues from the start of the road. Rhaetic units retain legal status as customary measures for alcoholic beverages which are typically served in bochè and bossl.

The Royal Trading Standards Decree 1716 invalidated the various measures used across the Kingdom of Tirol, declaring them to be replaced by statute measures based around the Rhaetic mesura (ms), a unit based upon the previous Inn bira mesura, the measure used for beer in the Duchy of the Inn. The mesura was established as the volume of x of water at 17°C (x).
