SVG imported too small or too big: find the cause from the number
Divide the size your software shows by the size you expected. About 0.75 or 1.33 means the file is written in pixels and two programs assumed different pixels per inch (72 and 96); 2.54, 10 or 25.4 means inches, centimeters and millimeters were mixed up. Select all of it, close the lock and type the intended width back.
