Standard US unit for quoting rent and other office economics.
Per square foot per year is the standard US convention. Per square foot per month is the standard in Hong Kong, India. PSF figures should always be qualified by RSF or USF basis — they are not interchangeable.
Per square foot (PSF) is part of the measurement vocabulary that institutional Class A occupiers, landlords, and advisers use across US markets. Understanding it correctly affects how you read lease documents, model occupancy economics, and benchmark deal terms across cities. Class A Atlas tracks the US definition alongside the global standard so cross-border occupiers can translate quickly.
