Question

rewrite the following measurements without using a side SI prefixes i) 1 pm ii) 12 Gm. iii) 1nm iv) 10 Tm​

Answer 1

SI prefix tables contains 10+10 SI prefixes. First table contains multiple prefixes (they are bigger than base unit) and submultiple prefixes (smaller than base unit). You can find examples below tables:

Examples:

1 hm = 1×102 m = 100 m2 kN = 2×103 N = 2000 N5 MHz = 5×106 Hz = 5 000 000 Hz
