【評論內容】好啦 特別去NIST（美國國家標準暨技術研究院）查〝Heat Release Rate (HRR) is the rate at which fire releases energy - this is also known as power. HRR is measured in units of Watts (W), which is an International System unit equal to one Joule per second. Depending on the size of the fire, HRR is also measured in Kilowatts (equal to 1,000 Watts) or Megawatts (equal 1,000,000 Watts).〞就認是瓦特囉！參考資料-NIS...
