Primary unit for Force (Eng) - Answers -Pound-force (lbf)
luminance - Answers -candela per squared meter (cd/m²)
absolute viscosity - Answers -Pascal second (Pa*s)
kinematic viscosity - Answers -square meter per second (m²/s)
moment of force - Answers -Newton meter (N*m)
surface tension - Answers -Newton per meter (N/m)
heat flux density - Answers -Watt per Squared meter (W/m²)
Entropy - Answers -Joule per Kelvin (J/K)
specific entropy - Answers -Joule per kilogram Kelvin (J/kg*K)
specific energy - Answers -Joule per kilogram
thermal conductivity - Answers -Watt per meter Kelvin (W/m*K)
energy density - Answers -Joule per cubic meter (J/m³)
electric field strength - Answers -Volt per meter (V/m)
electric charge density - Answers -couloumb per cubic meter
electric flux density - Answers -couloub per square meter (C/m²)

Relationship between mass and weight - Answers -W=mg where g is the gravitational
constant; mass remains constant and is an inherent property of the item, weight is
dependent upon the value of g at a given location
, Gravitational constant on earth (English and SI) - Answers -g = 32.2 ft/sec²; 9.81m/s²
Note on consistent and inconsistent units - Answers -Using consistent units is
preferable but may not be needed. When inconsistency arises, simply be sure to note
when conversion factors are needed.
