高度是垂直距離的度量,可以是垂直範圍(某物或某人有多“高”)或垂直位置(一個點有多“高”)。 例如,“該建築物的高度為50米”或“飛行中飛機的高度約為10,000米”。 例如,“基斯杜化·哥倫布的垂直高度為 5 英尺 2 英寸”。

當該術語用於描述垂直位置(例如飛機的)距離海平面的高度時,高度通常稱為海拔[1] 此外,如果該點與地球相連(例如山峰),那麼海拔(距離海平面的高度)稱為相對高度[2]

在笛卡兒座標系中,高度是沿垂直軸()在特定點和另一個不具有相同值的點之間測量的。如果兩個點恰好具有相同的值,則它們的相對高度為零。在三維空間的情況下,高度是沿垂直軸測量的,描述了與-平面(或上方)的距離。
