Well, honey, you can measure that 750mm ribbon with a 30cm ruler by simply lining it up three times and adding the measurements together. It's not rocket science, just basic math. So, get your ruler out, start measuring, and stop stressing over the small stuff.
1 cm = 10 mm. Start with ruler at 0 and mark ribbon at 30 cm. Then place ruler at the mark and measure 30 cm more and make another mark- you are up to 60 cm or 600 mm. Then place ruler at this mark and measure 5 cm, or 50 mm. Now you have a 650 mm ribbon.
