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.*.
(There are about 5 million scientists and engineers in the U.S.) Thus the median engineer salary of $60 - $70 K per year is roughly twice the median salary for all jobs in the U.S. of ~$30 K per year (see General Income Information).he figure above gives 1996 Total Salaries (base salaries plus bonuses) of All Engineers, All Degrees, from the Engineering Workforce Commission of the American Association of Engineering Societies. Curves for the 10, 25, 50, 75 and 90 th percentiles are shown and identified in the legend.
