Chapter 10

Mass and Force Measurement

Richard Leach

This chapter discusses precision mass and force measurement. After a short history of mass metrology, the chapter discusses the current mass traceability through the kilogram, its use and dissemination. The limitations of the current mass definition are discussed along with introductions to the alternative realisations: the Watt balance and Avogadro approach. Standard mass comparators and low-mass measurement are also covered. The second half of the chapter discussed low-force measurement. Natural low-force mechanisms are presented along with the low-force traceability infrastructure: primary low-force balances and transfer artefact types.
