The circumference of the earth is 25,000 mi at the equator. What is the circumference in kilometers? in meter?
 I really don't understand how to concer this. Please help!

1 mile = about 1.61 km.
Multiply: 25,000 * 1.61 = ? km
1 km = 1,000 m
Multiply your km answer by 1,000. 
To be more accurate for the meters 
1 mile = 1 609.344 meters
Multiply: 25,000 * 1,609.344 = ? m 
ok um im still a little confused.
is kg and km the same thing as kilometers?
and...
are those the steps you gave me to figure it out? 
kg = kilogram (measures mass)
km = kilometer (measures distance)
Yes. Follow the steps I gave you to find the answers. 
thanks for clearing that up for me!
when i multiplied km by 1000 i ended up getting 40250000
but when i mutiplied 25000x1609.344 i ended up getting 40233600
Which one is the right answer? 
The more accurate answer is 40,233,600 meters. But many teachers would probably accept the other answer, also.

Thank you so much!
You really did help me ! 
You're very welcome.

Is that 40250000 is the right answer.
