- The metric system is based on units of 10. Count zeros. Consult the metric ladder as to how many spaces to move the decimal point.
- Move the decimal left when converting from a smaller to larger value (DIVIDE)
- Move the decimal right when converting from a larger to smaller value (MULTIPLY)
One meter is how many kilometers? The question involves going from a smaller value (meter) to a larger value (kilometer). Move the decimal to the left (divide)
1.0 meter = .001 kilometers = 1 X 10-3 kilometers
How many millimeters are in 5 meters? The question involves going from a larger value (meters) to a smaller value (millimeters). Move 3 decimal places to the right (multiply).
5.0 meters = 5000 millimeters = 5 X 103 millimeters
How many liters are in 80 nanoliters? The question involves converting a small value (nanoliters) to a larger value (liters). Move the decimal to the left 9 places
80. nanoliters = .00000008 liters = 8 X 10-8 liters
