The most commonly used scale to measure drought is the Palmer Drought Severity Index (PDSI). It takes into account factors such as temperature, precipitation, and soil moisture to determine drought severity. The scale ranges from -10 (extremely dry) to +10 (extremely wet), with zero indicating normal conditions.
