Mass measurement doesn't always need massive equipment. Unlike traditional balances that rely on physical weights, the NIST-4 Kibble balance uses electrical currents and voltages to precisely measure mass, making it more accurate and stable over time. The Kibble balance, originally a massive research project, has been a game changer. However, its size and cost have made it inaccessible to many. Recognizing this limitation, NIST set out to make this technology more widely available by creating a
