SI Conversions • Use the prefix line of King Henry died by drinking chocolate milk! • K h da b d c m • This gives you the number of places and direction to move the decimal when doing a SI conversion
Example #1 • How many kilograms are there in 45, 456 mg K h d b d c m So…move the decimal 6 places to the left 45,456 mg = 0.045456 kg
Mega – khdbdcm – micro – nano – pico x3 x3 x3 x3 Doing conversions using the “other” prefixes Example #2 - How many meters are there in 6500 nanometers? K h d b d c m μ n = 6.5 x 10-6 m
Example #4 How many m3 is 650 cm3? K h d b d c m So…move the decimal 6 places to the left 650 cm3 = 6.5x10-4 m3 = 0.00065 m3
