2. HR (capital letters) stands for "human resources", the part of a company that looks after hiring and workers. [tree →](https://mova.elamur.ai/free/en/corpora/dictionaries/school/H/hr/#m2)

### In the lessons

In maths, timetables and science tables: "2 hrs 30 min", speed in "km/hr" (better "km/h"). On signs: "24 hr shop". HR appears in grown-up work talk. It is read aloud as "hour(s)".

### Note

Abbreviation, not a word; in full writing say "hour". 1 hr = 60 min; 1 hr = 3600 seconds; 24 hrs = 1 day. Scientists usually write "h" not "hr". Trap: "hr" is not a whole number of minutes in decimals: 1.5 hrs = 90 min, not 150.
