The A*STAR’s National Metrology Centre (NMC) is the national measurement institute of Singapore, dedicated to advancing measurement science for an innovative and competitive economy
NMC establishes, develops, maintains and disseminates the national measurement standards traceable to the International System of Units, providing key support to a wide spectrum of industry.
Achieving the nation’s highest level of physical measurement through close collaboration with leading national and international organisation.
With a multidisciplinary team of experienced scientists and engineers and state-of-the-art facilities, NMC provides dedicated services to industry partners to meet their specific needs.
NMC believes in working in close collaboration with industry partners, to create values for them and fuel growth for the industry.
Quantity measurements are important to our daily life. Items such as food, medicine, water, oil and precious metal and others are traded in terms of "mass". Contemporary mass measurements are critically required for commerce, technology, and science. The Mass quantity is defined by "International Prototype of Kilogram (IPK)" and is disseminated to mass-related derived measurement quantity such as force, hardness and pressure etc.
NMC maintains the No:83 of copier of IPK, and is able to provide the measurement and calibration from 1mg to 50 Kg with smallest uncertainty in Singapore. This is important to the industries. For example, a very small error in quantity will lead to huge amount lost for a pharmaceutical production. Force measurements are also widely used for construction, civil engineering and transportation.
The Mass & Force Laboratory develops, maintains and disseminates the mass, force, torque, hardness and density metrology-related national standards in Singapore.
NMC realises the kilogram, which is the base unit of mass, with the Singapore's Kilogram No. 83 traceable to the International Prototype Kilogram in Paris.
The value of mass is transferred to other mass standards through a series of comparisons (using mass or vacuum mass comparators), involving combination of mass standards in sub division or addition to achieve different mass values.
The standards are capable of calibrating the mass standards from 1 mg to 20 kg with expanded measurement uncertainties (k = 2) from 0.6 μg to 1.3 mg.

NMC realises the newton (N), which is the unit of Force derived from mass (kg) and gravitational acceleration (m/s2), through the use of deadweights exerting a direct force on a transfer standard (force transducer).
High capacity forces are achieved in NMC by using forces generated by deadweights amplified through a lever system.
The standard is capable of calibrating force devices from 1 mg to 20 kg with expanded measurement uncertainties (k = 2) from 0.6 μg to 1.3 mg.
