Tuumamääräinen

Tuumamääräinen is a Finnish term that translates to "inch-based" or "measured in inches". It refers to a system or measurement where quantities are expressed using inches as the unit of length. This contrasts with the metric system, which uses meters and centimeters.

In various contexts, "tuumamääräinen" might indicate that a particular object, specification, or standard is defined by its dimensions in inches. For example, a piece of lumber might be described as "tuumamääräinen" if its dimensions, such as width and thickness, are given in inches rather than millimeters. Similarly, engineering drawings or product specifications could use this term if the measurements are consistently in inches.

The use of "tuumamääräinen" often implies a connection to or origin from systems that predominantly use imperial units. While Finland officially uses the metric system, there can be situations, particularly with imported goods or specific industries, where imperial measurements are still encountered and referred to using this term. It signifies a deviation from the standard Finnish measurement system.
