Mass is the amount of matter in an object. In the metric system, we use grams and kilograms to measure mass.
Mass is different from weight. Mass stays the same regardless of location, while weight can change with gravity.
The metric system uses a base-10 structure, making conversions between units straightforward.
Remember that "kilo" means one thousand, so 1 kilogram equals 1,000 grams.
Converting between metric units involves moving the decimal point left or right based on the conversion factor.
When converting from kilograms to grams, you're multiplying by 1,000, so the number gets larger. When converting from grams to kilograms, you're dividing by 1,000, so the number gets smaller.
To compare measurements with different units, convert them to the same unit before making comparisons.
Always double-check that you've converted all measurements to the same unit before comparing them.
Apply your knowledge of metric mass conversions to solve practical problems.
When solving multi-step problems, write down each conversion to avoid errors.
