  2. Scientific Notation Terra x 1012 T 1 000 000 000 000 Giga x 109 G 1 000 000 000 x 106 Mega M 1 000 000 kilo x 103 k 1 000 x 100 Units Eg. meters 1 milli x 10-3 m 1 / 1 000 x 10-6 micro μ 1 / 1 000 000 x 10-9 nano n 1 / 1 000 000 000 pico x 10-12 p 1 / 1000 000 000 000

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

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

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

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

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

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

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

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