To solve these problems, we need to convert between different metric units. Here are the main rules to remember:
*
Mass (Weight):
* 1 kilogram (kg) = 1,000 grams (g)
* To go from kg to g, multiply by 1,000.
* To go from g to kg, divide by 1,000.
*
Length:
* 1 kilometer (km) = 1,000 meters (m)
* 1 meter (m) = 100 centimeters (cm)
* 1 centimeter (cm) = 10 millimeters (mm)
* So, 1 km = 1,000,000 cm and 1 km = 1,000,000 mm.
*
Volume (Capacity):
* 1 Liter (L) = 1,000 milliliters (mL)
* To go from L to mL, multiply by 1,000.
* To go from mL to L, divide by 1,000.
Let's solve each problem step-by-step:
