您係冰度讀小學架？【詩經】就有分【大雅‧小雅】啫，科學都要分大小雅茄？

回復 #6 酒井明的帖子

冇咁快喎。照定義係：Speed of light set by definition

In 1983, the 17th Conférence Générale des Poids et Mesures adopted a standard value, 299,792,458 m/s for the speed of light. This in turn defines the length of a meter in terms of the speed of light, so that further refinements in the current experimental value of the speed of light actually would just refine the definition of a meter.

用不同測量法可得出一些偏差，但都冇38萬km/s, 30萬才是較準的ball park figure
