Sebességmérk

Sebességmérk is a Hungarian term that translates roughly to "speed marker." The expression is not widely established as a formal term in Hungarian technical literature and is more likely to appear in informal or context-specific writing. In general, it can refer to any device, symbol, or mark that indicates a particular speed value within measurement systems, displays, or data records.

In instrumentation and calibration, a sebességmérk may denote a mark on a scale or a highlighted readout that corresponds to a chosen velocity during testing or data logging. For example, on an aerodynamics or flow measurement instrument, a sebességmérk could be a calibration mark set at a specific speed to aid quick reading or verification. The concept is related to how measurement systems present velocity information, rather than describing a distinct, standardized device.

In road testing or traffic engineering contexts, the phrase may appear in descriptive texts to refer to speed indicators or target speeds used in experiments. However, standard Hungarian terminology in such contexts typically uses sebességmérő (speedometer or speed-measuring device) or terms related to speed limits, rather than sebességmérk.

Etymology: the term combines sebesség (speed) with mérk, a root related to marking or measurement, yielding “a marker indicating speed.” Given its rarity, the exact meaning of sebességmérk can vary by author and discipline.
