Frequently asked questions
What is a scale factor?
A scale factor is the number used to multiply an original measurement to produce a proportional scaled measurement.
How do I know whether the result is an enlargement?
If the scale factor is greater than 1, the new size is larger. If it is less than 1, the new size is smaller.
Can I use different measurement units?
Both values should use the same unit before calculating. Convert one value first if the units are different.
