A Tale of Two Systems
The world primarily uses the Metric System (SI), known for its base-10 simplicity (1000m = 1km). The US uses the Imperial System (12 inches = 1 foot, 5280 feet = 1 mile).
Why It Matters
Conversion errors can be catastrophic. In 1999, NASA's Mars Climate Orbiter disintegrated in the Martian atmosphere because one team used English units (pound-seconds) while another used Metric units (newton-seconds).
Temperature
- Celsius: Water freezes at 0° and boils at 100°.
- Fahrenheit: Brine freezes at 0°, water freezes at 32°.
- Kelvin: Absolute zero (-273.15°C) is 0K. Used in science.
