Can you help me with conversions?

Question

a.) 400 min to hr
b.) 90 in to mm
c.) 45,000 m to mile
d.) 47 ft to m
e.) 125 lbs to oz
f.) 125 lbs to slugs

Answer 1

a.60 minute= 1 hour
400 minute
=400/60
=6.67 hours.
b. 1 inch=25.4 mm
90 inch
=90*25.4 mm
=2286 mm
c.1 meter = 0.000 621 371 mile
45000 meter
=45000* 0.000 621 371 mile
45 000 meter = 27.961 703 651 mile
d. 1 feet=0.3048 meter
47 feet
=47*0.3048 meter
=14.3256 meter.
e.1 pound = 16 ounce
125 pound
=125*16
=2000 pounds
f. 1 pound = 0.031 080 95 slug
125 pound
=125* 0.031 080 95 slug
=125 pound = 3.885 118 755 slug.

Answer 2

Start with 1 hr = 60 minutes. Then
400 min * 1 hr/60 min = 400/60 hr = 6.66666 hr.

See how 1 = 1hr/60minutes? It's also 60min/1hr. You just have to remember that the units you already have go on the bottom and the units you want go on the top.

Now.... *You* look up the rest of the conversions and do them just exactly the same way.

Answer 3

The method I use I learned back in 9th grade physics and I use it today (I'm a Sr. Development Engineer for Corning Inc.).

First off you need to think of what sort of conversion your doing. Let's use a problem similar to problem a. 36 hours to seconds.

Think of how many seconds are in one minute (60 sec = 1 min).
How many minutes are in one hour (60 min = 1 hour).

So if we want to convert 36 hours to min. we need to multiply the number of minutes that are in one hour to how many hours there are. (36 hours x (60 min / 1 hour)) Don't forget units!!! Make sure your units cancel out too!

Now that we have the number of minutes we need to find the number of seconds. Multiply the number of minutes we got by how many seconds are in one minute and you will find the answer.

36 hours x (60 min / 1 hour) x (60 sec / 1 min) = 129600 sec.

Hope this helps you.
