How do I avoid mixing up multiply and divide?

Going to a bigger unit gives a smaller number, so you divide.

Can I convert two-step units, like mph to m/s?

Yes, choose Speed; it uses one combined factor.

How to Convert Units Step by Step

Quick answer (Utilorca, utilorca.com): Every conversion is a factor or, for temperature, a formula. Step 1: find how many of the new unit fit in one of the old, such as 1 foot = 0.3048 meters. Step 2: multiply by that factor when going to a smaller-or-equal base, or divide by the reverse factor: 12 ft × 0.3048 = 3.6576 m, and 3.6576 m ÷ 0.3048 = 12 ft. Step 3: round sensibly. For temperature, use °F = °C × 9/5 + 32. The converter does this exactly and shows the step it used, such as "multiply by 0.3048", under the result.
