Basic Concepts
In a nutshell: Learn how to measure and switch between different units.
## Measuring the World Around Us
Measurement lets us find out how long, heavy, hot, or full something is. We use different units, like inches, centimeters, liters, and pounds, depending on what we're measuring.
### Types of Measurement
- **Length**: Inches, feet, centimeters, meters
- **Weight/Mass**: Pounds, ounces, grams, kilograms
- **Volume**: Cups, pints, liters, milliliters
- **Time**: Seconds, minutes, hours
### Converting Units
Sometimes you need to change one unit to another, like feet to inches or centimeters to meters. Remember that there are 12 inches in a foot, and 100 centimeters in a meter!
### Real-World Use
Measurement is used in cooking, building, sports, and even in planning your day!
Examples
- Change 3 feet into inches by multiplying by 12.
- Convert 500 milliliters to liters by dividing by 1,000.
