How to use
Pick a direction, then enter the distance and the scale. At 1:100, 100 mm on paper means 10 m in reality. Measure one point on the plan and compare before trusting the figure, because paper mistakes grow fast at large scales.

Drawing Scale Converter Guide
This guide converts drawing measurements to real lengths in your browser. Enter a paper line with a ratio like 1:50 to get true size in centimeters and meters. Reverse math turns site sizes into plan sizes. Reading denominators correctly is critical; mixing 1:50 with 1:100 doubles results. Measure from one print.
