A scientific measuring instrument for determining the size, height, or precise measurements of peaks, extremities, or pointed structures.
From Greek 'akron' (peak/extremity) + 'metron' (measure). This instrument term combines the prefix for extremity with the standard measuring suffix used in scientific instruments.
Scientists actually use special tools to measure mountain peaks and extremities with incredible precision—acrometers help them track how tallness changes due to geological processes!
