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.
Femtogram
A femtogram (fg) equals 10^-18 kilogram.
From the SI prefix 'femto-' (from Danish/Norwegian 'femten', fifteen).
Nanotechnology and high-sensitivity mass spectrometry.
The femto- prefix was adopted by the CGPM in 1975.
