The correct conversion of the following length units is ()
A. 9.6nm=9.6×10-3=9.6×10-3μmB. 9.6cm=9.6×10mm=96mmC. 9.6cm=9.6cm×10=96mmD. 9.6cm=9.6÷100dm=0.096m


A. In the process of conversion, it should be 9.6nm = 9.6 × 1 × 10-3 μ M = 9.6 × 10-3 μ m, so this option is wrong; B. in the process of conversion, it conforms to the unit conversion format, so this option is correct; C. in the process of conversion, it should be 9.6cm = 9.6 × 10mm = 96mm, so this option is wrong; D. in the process of conversion, it should be 9.6cm = 9.6 × 0.01M = 0.096m, so this option is wrong; B
