How do you calculate a scale?

Calculating the Scaled Distance using the Actual Distance. If the scale is 1 : x, then divide the actual distance by x to calculate the map distance.

How do you figure out the scale factor of a dilation?

Dilation scale factor 2: Starting with ΔABC, draw the dilation image of the triangle with a center at the origin and a scale factor of two. Notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). Dilation with scale factor 2, multiply by 2.

What is the difference between the scale and the scale factor?

Two triangles are similar if the lengths of the corresponding sides are proportional; that is, if a = kp, where k is a constant, then b = kq, and c = kr. In this case, the constant k is the “scale factor.” The scale factor describes the relationship between the two similar triangles.
