To convert time to just minutes: 1  2 hours is 2 hours * (60 minutes / 1 hour) = 2 * 60 minutes = 120 minutes. 2  45 minutes is 45 minutes * (1 minute / 1 minute) = 45 * 1 minutes = 45 minutes. 3  45 seconds is 45 seconds * (1 minute / 60 seconds) = 45/60 minutes = 0.75 minutes.
The average mechanical engineer in the United States earned $38.74 per hour, which comes to $80,580 per year as of 2009. The BLS reported earnings of $49,730 for lowest-earning tenth percentile and $117,550 at the top or 90 percentile level, a difference of over $67,000 per year.*.
Junior engineers make between 40 and 50 thousand dollars per year. Regular engineers make between $50 -70 tho â¦ usand and master engineers make between $70 to 95 thousand. An electrical engineer will make an average of 70,000 dollars a  year.How much an electrical engineer makes depends largely on  experience, education and the industry in wh â¦ ich the person chooses  to work.     I would say $ 60,000 is a low estimate since the BLET national agreement pays around $ 2600 â¦ per every two weeks on the extraboard. That alone is $68,000 per year for an extraboard engineer. Yard enginners tend to make a little less but road engineers make a lot more.
