Introduced in 1976 at the height of the United States' metrication hysteria, the Better Ideas New American Metricaddy is a later iteration of the Creative Workshop Universal Circle Metric Converter. The Universal Circle Metric Converter was designed by Ole Jorgensen in 1970, and introduced alongside his better-known Universal Circle Slide Rule. Both of these devices share a similar pencil cup form factor and slide function. The New American Metricaddy adds a number of conversion factors not present on the original Creative Workshop device, and is capable of converting among 40 different units of measure. The New American Metricaddy has a three-part stator printed with conversion units, and two rotating slides printed with logarithmic scales.
