Unit Conversion and Prefix Calculations
Learning Objectives
- Students will be able to convert between SI units using prefixes
- Students will understand the powers of 10 in SI prefixes
- Students will be able to perform unit conversions using dimensional analysis
Core Concepts
- SI prefixes represent powers of 10
- Converting between different scales (km to m, mg to g, etc.)
- Using conversion factors in calculations
Formulas
$$Q_{new} = Q_{old} \times k$$
Basic formula for unit conversion
Interesting Fact
Non-metric conversions (like inches to feet) require remembering specific factors
Key Scientist
Jean-Baptiste-Joseph Fourier
Demonstrated the power of systematic dimensional analysis in physics
Modern Research
Computational chemistry and physics routinely convert between unit systems, such as using atomic units (au) in quantum chemistry for computational efficiency.
