   A PAR56, for example, is 56 eighths of an inch (7 inches) in diameter; a PAR36 is 36 eighths (4.5 inches) in diameter, and so on. Similarly, the diameter in millimeters can be found by multiplying the PAR designation by 3.175. For example, a PAR16 lamp is approximately 2 inches or 50.8 mm in diameter. [1]

   They are also found on some RVs for connecting to shore power. RVs in the US are equipped for 120 V 30 A or 240 V 50 A service, and use a cord to connect to a receptacle at the campsite, usually on a power pedestal with one or more receptacles providing 120 V 30 A (TT30R), 240 V 50 A (14-50R), or 120 V 15/20 A (5-20R) service.

   Its capacity is normally around 1,000 kg or 2,200 lb, but the larger units can store even more. A FIBC designed to transport one metric ton (0.98 long tons; 1.1 short tons) of material will itself only weigh 5–7 lb (2.3–3.2 kg). Transporting and loading is done on either pallets or by lifting it from the loops. Bags are made with either one ...
