Questions this course answers

What selects the orientation of a conversion factor?

Writing the unwanted unit on the opposite side makes it cancel algebraically.

How does area change a length conversion?

Area contains two length dimensions, so both number and unit are squared.

Why is density useful in conversions?

Density has mass-per-volume units that can bridge those quantities.

Why do absolute temperature conversions need an offset?

Absolute scales differ in both interval size or convention and reference zero.

What is the quickest error check?

An estimate reveals reversed factors and implausible magnitudes.
