decimalseconday

A decimalseconday is a proposed unit of time, conceived as a subdivision of the second. The name itself suggests a decimal relationship to the standard SI second, meaning it would be one-tenth of a second. This unit is not officially recognized by the International System of Units (SI) and therefore has no specific symbol. Its primary purpose would be to offer a more granular measurement of time in contexts where the millisecond or microsecond might be too large, but the full second is clearly insufficient.

The concept of decimalseconday aligns with the decimal system's pervasive use in scientific and engineering fields. It would fall between the millisecond (10^-3 seconds) and the centisecond (10^-2 seconds), representing 10^-1 seconds. While centiseconds are already established as a standard SI prefix, the decimalseconday fills a conceptual gap in certain applications, though its practical necessity is debated. In everyday usage, and even in most scientific disciplines, existing units like milliseconds are generally sufficient for most time-measuring needs. The development and adoption of such a unit would likely depend on the emergence of specific technological or scientific requirements that necessitate this precise level of temporal resolution.
