Convert Days, hours & minutes to hours

[vivs2010]

Hi All,

I have a big data in excel with the below data and i need to convert them in minutes. Examples below:-

1H 28M - 60minutes + 28minutes = 88minutes

1D 5H 54M - 24 hours (1440 min) + 5 hours (300 min)+ 54 minutes = 1794 min

Can someone help me what formula i can apply here?

Sorry guys - the heading is slight misleading. It is convert days, hours & minutes to "Total minutes"
