BACnet engineering units list

Updated 7 November 2026

Short answer

A BACnet analog object reports its units as a number. Scans, EDE files and some front ends show that number instead of the unit. Find any of them here. Examples: 0 = square-meters, 1 = square-feet, 2 = milliamperes.

Looking for a number but not sure which list it belongs to? Use the BACnet number lookup, which searches every table at once.

Values come from the open-source bacnet-stack 1.6.1 (bacenum.h), which follows ANSI/ASHRAE Standard 135, and were cross-checked one by one against two other independent BACnet stacks (bacpypes and @bacnet-js/client). Entries marked (newer) are in bacnet-stack only, because the other two stacks predate them. Numbers 0-255 (and the higher ASHRAE ranges) are standard; vendors may use proprietary numbers above them.
