Activity unit H and HR

1380 Views

Hi guys,

I have a generic query. We have activity unit H for Hour and HR for Hours also D for day and day for days. But I can use 5H for 5 Hour and 5HR for same 5 hours of activity time. Than why both the units are given in the standard system. If both can serve the same purpose.

Let me know if 25 HOURS can be used both as 25H and 25HR.

Expecting a quick reply

Thank you.
