Concept explainers
(a)
Interpretation:
Convert 2600 mmHg to psi
Concept introduction:
One-unit system is usually used in science but less generally used in daily life, is called the 'SI' system or ‘International system’. The other system is the metric system widely used in United States.
Conversion tables can be used to directly convert values of these two systems.
From unit conversion tables we can get the following relationships.
1 mmHg is the pressure exerted by a 1 mm vertical column of mercury (Hg) and ‘psi’ is the pressure which results from a force of one pound apply to one square inch area.
