Pressure measurement
Many other hybrid units are used such as mmHg/cm or grams-force/cm (sometimes as kg/cm without properly identifying the force units). Using the names kilogram, gram, kilogram-force, or gram-force (or their symbols) as a unit of force is prohibited in SI; the unit of force in SI is the newton (N).
Torque
Torque has dimension force times distance, symbolically . Official SI literature suggests using the unit "newton metre" (N⋅m) or the unit "joule per radian". The unit "newton metre" is properly denoted N⋅m or N m. This avoids ambiguity with mN, millinewtons.
