Practice10 grams to kilograms

500 milliliters to liters

65 hectometers to millimeters

TipsWhen using the conversion factor, the bigger

number goes with the smaller unit i.e 1000 mm in 1 m

When going UP the ladder, bigger number goes on the bottom of the conversion factor

When going DOWN the ladder, bigger number goes on the top of the conversion factor
