Questions and answers

What type of measurements must be used in dimensional analysis?

Units must be the same type of measurement, i.e. measurement of length to length, weight to weight. (paragraph 1)

How should like units be arranged in a conversion formula?

Make sure like units (Gallons/Gallons) are on opposite ends of the fraction (numerator/denominator). (paragraph 3)

What metric conversion example uses multiplication by 1000?

Example: if converting milligrams (10-3) to micrograms (10-6) you would multiply by 1000. (paragraph 4)
