NIST is the National Metrology Institute for the United States, also known as an NMI. Everything you use in your everyday life works because of measurements. Without precise measurements, your car wouldn’t run, your phone wouldn’t work, and hospitals couldn’t function. We maintain the measurements that make industry and society work.
