A
SI (International System of Units)
B
Imperial System
C
CGS (Centimeter-Gram-Second) System
D
US Customary Units
Verified step by step guidance1
Understand that the question asks about common systems of units used by engineers for scientific measurements.
Recall that the SI (International System of Units) is the globally accepted standard system for scientific and engineering measurements, based on meters, kilograms, seconds, etc.
Recognize that the Imperial System and US Customary Units are primarily used in everyday measurements in some countries but are not standard for scientific work.
Note that the CGS (Centimeter-Gram-Second) system is an older metric system used in some scientific contexts but is less common than SI in engineering.
Conclude that the SI system is the most widely used and accepted system for scientific measurements in engineering.
