Modern instruments generally report charge in SI units, limiting the routine use of this conversion
-
Care is needed to avoid misinterpretation due to differences in unit scale
Frequently Asked Questions
-
What does 1 ampere-second represent?
-
1 ampere-second (A*s) is the SI derived unit of charge equal to the charge transported by a current of one ampere flowing for one second, which equals exactly one coulomb.
-
What is the relationship between EMU of charge and coulombs?
-
One EMU of charge (also called an abcoulomb) equals 10 coulombs in the SI system.
-
Why convert from ampere-seconds to EMU of charge?
-
Converting allows translation of modern SI charge measurements to CGS-EMU units for comparison with older scientific data or theoretical models using the CGS system.
Key Terminology
-
Ampere-second [A*s]
-
The SI derived unit of electric charge corresponding to the quantity of charge moved by a steady current of one ampere in one second, equal to one coulomb.
-
EMU of charge
-
A unit of electric charge in the CGS-EMU system also called abcoulomb, equal to the charge carried by one abampere in one second, and equal to 10 coulombs in SI.
-
CGS-EMU system
-
A measurement system using centimetre–gram–second units for electromagnetic quantities, where EMU of charge is a common unit.
