Fyllgrad

Fyllgrad is a term used to describe how full something is relative to its capacity. In Swedish, it refers to the degree or level of filling and is defined as the ratio of the actual amount present to the maximum amount the container or system can hold. It is typically expressed as a percentage or a fraction.

Calculation and interpretation: Fyllgrad = (actual amount) / (maximum capacity) × 100%. For discrete counts, it can be expressed as a percentage of items or as a fraction. A fyllgrad of 75% means the container or system is three quarters full, and 100% indicates a full capacity, while 0% means empty.

Applications: The concept is used across several domains. In logistics and process industries, fyllgrad describes how full tanks, silos, bins, or hoppers are, and it informs replenishment and process control. In warehousing and inventory management, it can indicate storage utilization. In information technology, fyllgrad may describe resource usage such as disk or memory utilization, or data capacity usage. In manufacturing, it helps monitor feed rates and buffer stocks to optimize throughput and avoid overflows or shortages.

Measurement: Fyllgrad is typically measured with level sensors (ultrasonic, radar, capacitive), float gauges, weight measurements, or software-based inventory data. The accuracy of the fyllgrad reading depends on sensor quality, measurement interval, and whether the content is homogeneous or prone to stratification or settling.

Related concepts: Fill level, fill factor, occupancy rate, and utilization are analogous terms used in different contexts to express how much of a capacity is currently in use. See also capacity planning and inventory control.
