The easy-to-read RulerTM adds numerous small innovations that make a big difference in usability. On the English side, the 1/4", 1/8", and 1/16" hash marks are counted, and labeled lines eliminate guesswork. On the metric side, both millimeters and centimeters are marked with numbers and hash marks, making it easy to identify millimeter sizes. The English and metric rulers start at the edge, making conversions easy. A quick glance at the ruler shows you what you need. The metric side is black, and the English side is composed of a variety of vibrant colors, so there's no confusion about which side is which. The use of high-contrast, vibrant colors works well on any surface. All these changes together make measuring simple, quick, and accurate.
