Units explained
Kilogram-force square second/meter
The kilogram-force second-squared per meter (the hyl or TME) is about 9.807 kg.
The mass unit of the metric gravitational (technical) system.
Older continental European engineering practice.
Used in the metric technical system before SI adoption.
Attogram
An attogram (ag) equals 10^-21 kilogram.
From the SI prefix 'atto-' (from Danish 'atten', eighteen).
Frontier nanoscience and single-molecule mass detection.
The atto- prefix was adopted by the CGPM in 1975.
