It wasn't until the mid 20th century that the use of the Accordion, Goombay Drums, and
Pounds per square inch be added to any pressure reading made in air at sea level. The converse is pounds per square inch gauge (psig), indicating that the pressure is relative to atmospheric pressure. For example, a bicycle tire pumped up to 65 psig in a local atmospheric pressure at sea level (14.7 psia) will have a pressure of 79.7 psia (14.7 psi + 65 psi). When gauge pressure is referenced to something other than ambient atmospheric pressure, then the units would be pounds per square inch differential (psid). The kilopound per square inch (ksi) is a scaled unit derived from psi, equivalent to
