Data viva — SI units and pressure conversions
A Primary physics data viva — read an SI-base-units table and a pressure-conversion box; list the seven base units; convert 100 mmHg into kPa (about 13.3 kPa); distinguish the units used for blood pressure (mmHg), airway pressure (cmH2O) and cylinders (bar).

A reference diagram shows a table of the seven SI base units (Quantity, Unit, Symbol: Length/metre/m, Mass/kilogram/kg, Time/second/s, Electric current/ampere/A, Temperature/kelvin/K, Amount of substance/mole/mol, Luminous intensity/candela/cd) and a highlighted pressure-conversion box: 1 atmosphere = 101.325 kPa = 760 mmHg = 1033 cmH2O, with three clinical icons (BP cuff mmHg, airway gauge cmH2O, gas cylinder bar). Read the table, give the base units, and convert a blood pressure of 100 mmHg into kPa.
