How to use:

Current Size - size of the selection; area of the selected polygons in scene units and below in m2.
Get Size From Selection - transfer current size to fields X, Y, Z.
X, Y, Z - size along the axes; one field - proportional scale.
XYZ - the same size across all axes.
Keep bottom - the bottom point remains in place.
Scale individually - each object gets size separately when multiple objects are selected.
Scale - apply.
Pick 2 Points - specify two points in the viewport.
Length / Match Scale - make the distance between points equal to Length.
Reset XForm after scale - apply Reset XForm after scaling.
Clear - clear all fields.

Fields accept percentages (150% - one and a half times larger).
Each press - one step Ctrl+Z.
