Questions
- Are the conversions exact?
- The factors are the defined ones rather than rounded approximations.
- Why are there two kinds of kilobyte?
- Because there genuinely are.
- Why are US and UK pints different?
- They just are, and by a lot: a UK pint is about 20 percent larger.
- Why does temperature work differently?
- Because Fahrenheit has an offset as well as a scale, so it cannot be converted by multiplying alone.
