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!

Chemistry 
Ms. Sue,
1 mile = about 1.61 km.
Multiply: 25,000 * 1.61 = ? km
1 km = 1,000 m
Multiply your km answer by 1,000. 
Chemistry 
Ms. Sue,
To be more accurate for the meters 
1 mile = 1 609.344 meters
Multiply: 25,000 * 1,609.344 = ? m 
Chemistry 
Jecce,
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? 
Chemistry 
Ms. Sue,
kg = kilogram (measures mass)
km = kilometer (measures distance)
Yes. Follow the steps I gave you to find the answers. 
Chemistry 
Jecce,
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? 
Chemistry 
Ms. Sue,
The more accurate answer is 40,233,600 meters. But many teachers would probably accept the other answer, also.

Chemistry 
Jecce,
Thank you so much!
You really did help me ! 
Chemistry 
Ms. Sue,
You're very welcome.

Chemistry 
Riya,
Is that 40250000 is the right answer.
