Study the problem below, then continue.
220 mA = _______ A
Solution:
Substitute 10-3 for m and 10-6 for . Converting from 10-3 to 10-6 is a
NEGATIVE 3 change in exponent, so the decimal point in 220 must
move 3 places to the RIGHT.
NOTE:
Remember, when converting a metric prefix to a smaller metric
prefix, always move the decimal point to the RIGHT.
Thus:
220 milli amps becomes 220 X 10-3 amps when substituting 10-3 for
milli and 220,000 X 10-6 amps when substituting 10-6 for micro. Your
answer then becomes 220 milli amps = 220,000 micro amps.
