Is there an algorithm to get GUIs in scales instead of offset?

For example, I want to make my GUIs based off of scale instead of offset. So it's proportional on all monitor sizes. Is there any algorithm to do this? Would appreciate any help!

The first number of the X coordinate and Y coordinate is the scale, or to use it in a script, do

local frame = nil --insert frame here
frame.Position = UDim2.new(1, 0, 1, 0) --The 1's are the scale part.
