Pro Tip
Distinguishing 計る vs. 測る vs. 量る
In Japanese, the verb 計る (hakaru) is used for measuring time or numbers (e.g., 時間を計る, 点数を計る). 測る (hakaru) is used for measuring physical dimensions or distances (e.g., 身長を測る). 量る (hakaru) is used for measuring weight or volume (e.g., 体重を量る). Remember the context: time = 計る, physical dimensions = 測る, weight/volume = 量る.
Word Origin
The phrase combines 時間 (jikan, 'time') and 計る (hakaru, 'to measure'). 時間 derives from Middle Chinese 時問 (MC: dʐi H kˠuɐn), while 計る comes from Middle Chinese 計 (MC: keiH). The verb 計る itself has roots in Old Japanese, used for measuring or calculating durations.
Usage Notes

The verb 計る (hakaru) is specifically used for measuring time, whereas 測る (hakaru) is used for measuring physical dimensions or quantities.
