gram/minute [g/min] Unit Converter

Definition of gram/minute [g/min] unit

Gram per minute (g/min) is a mass-flow rate unit representing the transfer of one gram of substance during one minute. It equals 1.6667 × 10^-5 kilograms per second and is commonly used for small mass flows.

History of gram/minute [g/min] unit

The gram per minute developed from the metric system’s gram, introduced during the French Revolution as a practical mass unit based on the decimal system. As industrial measurement expanded, engineers combined mass units with time units to describe flow, producing expressions such as grams per minute. Although not an SI base or formally named derived unit, g/min remains a convenient decimal rate. Its usage became especially common in laboratory instruments, chemical processing, medical dosing, and environmental monitoring, where relatively small, controlled mass transfers needed clear reporting.

Applications of gram/minute [g/min] unit

Today, g/min is used to specify low mass-flow rates in laboratory pumps, chemical feeders, pharmaceutical dosing systems, and air or gas sampling equipment. For example, a device may deliver reagent at 2 g/min or inject a medication at a prescribed rate. Engineers also use it in calibration, material processing, and environmental monitoring when kilogram-per-second units are inconvenient.
