- 1,000 meters (m) = 1 kilometer (km)
- Volume:
- 1,000 milliliters (mâ„“) = 1 liter (â„“)
- 1,000 liters (â„“) = 1 kiloliter (kâ„“)
- Weight:
- 1,000 milligrams (mg) = 1 gram (g)
- 1,000 grams (g) = 1 kilogram(kg)
- 1,000 kilograms (kg) = 1 tonne (t)

Calculating Perimeter, Area and Volume
- Perimeter is the total distance around the outside of a shape.
- Area is the amount of surface a shape covers.
- Volume is the amount of space a three-dimensional object occupies.
Formulas
- Distance: Distance = average speed × time
- Volume of a Cylinder: Volume of a cylinder = π × ( radius )2 × height ,where π = 3.142
- Area of a Triangle: Area of a triangle = 1/2 × base × height
