Suction power can often be measured in units such as air watts (AW) or kilopascals (kpa), but they measure different physical quantities.
150aw is equivalent to 15kpa, while 16kpa is significantly higher than 15kpa, therefore, 16kpa has more suction power.
Air Wattage (AW).is a unit that measures the efficiency of the suction power of a vacuum cleaner, taking into account the power (flow rate and pressure) of the device. It is a more comprehensive measure of suction power, as its calculation is based on the vacuum cleaner's pumping power, while also taking into account the resistance when pumping. AW is calculated by the following formula:
Kilopascals (kpa).is a unit of pressure that directly measures the amount of negative pressure generated by the vacuum cleaner. The kilopascal is a commonly used unit of pressure in the world, equal to 1,000 Newtons per square meter.
If you want to compare which suction power is greater at 150 aw or 16 kpa, you can't compare it directly because they measure different aspects of suction power. In general, a higher AW value means that the overall cleaning efficiency of the vacuum cleaner is higher, while a higher KPA value indicates that the vacuum cleaner has more negative pressure, but the two do not correspond directly. In the absence of a specific conversion, it is impossible to directly say which one indicates the highest suction.
