Is there any simple vector drawing application that can let me make rough sketches with arbitrary units?

For example, I want to be able to draw a rectangle that is exactly 2’6 x 12".

If I scale it by 50% it should be 15" x 6". I want to be able to measure distances. I don’t want to keep track of a scale/conversion/ratio in my head, that’s a perfect job for computer.

In the old Sketchup software (RIP) you could type the measurements in while drawing or manipulating objects. It was extremely fast and intuitive. I don’t need 3d modelling; it was just a great UI.

All I can find is CAD and it is way overkill. Not gonna design a cotton gin or a circuit board. I just want to make a simple floor plan to see if the furniture would fit the way I want to arrange it. Or estimate material requirements for projects.

Desired features: Layers, customizable/smart keyboard shortcuts, colors, rectangle circle lines, transform/scale/skew/rotate, group/lock objects, rulers grids guide snapping.

anything?
