3. A way of making large numbers more manageable 100,000 Volts Kilo-Volts We divide the number by 1000 100,000  1000 = 100 kV Mega-Volts We divide the number by 1000 100  1000 = 0.1 MV

4. A way of making large numbers more manageable 1,245,000 Volts Kilo-Volts We divide the number by 1000 1,245,000  1000 = 1,245 kV Mega-Volts We divide the number by 1000 1,245  1000 = 1.245 MV

5. A way of making Small numbers more manageable 0.000,001 Volts milli-Volts We multiply the number by 1000 0.000,001 x 1000 = 0.001 mV micro-Volts We multiply the number by 1000 0.001 x 1000 = 1 µV

6. A way of making Small numbers more manageable 0.000,258,1 Volts milli-Volts We multiply the number by 1000 0.000,258,1 x 1000 = 0.258,1 mV micro-Volts We multiply the number by 1000 0.258,1 x 1000 = 258.1 µV

7. If we want to convert back to a base unit 1,245,000 µV mV We divide the number by 1000 1,245,000  1000 = 1,245 mV V We divide the number by 1000 1,245  1000 = 1.245 V

8. If we want to convert back to a base unit 1.25 MV kV We multiply the number by 1000 1.25 x 1000 = 1,250 kV Volts We multiply the number by 1000 1,250 x 1000 = 1,250,000 V

9. If we want to convert a number to a multiple above µV mV We divide the number by 1000 1.25  1000 = 1.25 µV 0.001,25 mV

10. If we want to convert a number to a multiple below mV V We multiply the number by 1000 1.25 x 1000 = 1.25 V 1,250 mV
