It's metres.

I suppose somebody young has inputted this mud map of the hospital to wall display computers around the Townsville Hospital, doubtless at a hefty cost to the public purse but a meter measures something, the unit of length which happily we only use multiples or sub-multiples of is the metre.

Thinking of sucking on the public purse I'd say inspecting a fire door every quarter doesn't come cheaply, chances are the inspections since 2007 that are displayed would cost as much as the door.
