Is air pressure 1000 HPA low pressure

yes. A standard atmospheric pressure is 1013hpa. If it is lower than this standard value, it is theoretically low pressure. If 1000hPa is lower than 1013hpa, it belongs to low pressure. Air pressure refers to the atmospheric pressure acting on a unit area. Is air pressure 1000hPa low air pressure? Common units of air pressure include: bar, Pascal, ATM, mmHg (Torr), kgf / cm2.

The air pressure is equal to the weight of the vertical air column extending upward to the upper boundary of the atmosphere per unit area. The size of the air pressure is related to height, temperature, etc.

Commonly used instruments for measuring air pressure in meteorological observation include mercury barometer, empty box barometer and barometer. (QiYa1000hpaShiDiQiYaMa)
