First multiply by 1000 to turn km into metres.
Then divide by the number of seconds in 1 hour.
3. 1km/hour is 1000m/hour, which is 1000m/3600s. So 1km/h = (10/36) m/s.
4. I LOVE YOU THANK YOU THANK YOU!!!!

Can do my mechanics homework now

THANK YOU!!!

edit-so that means conversion of km/-2 is the same except you divide by hours*2???

5. Sorry I don't understand what you mean!
6. Sorry if I had my acceleration in km per hour instead of the standard mertres per hour and needed to convert I would do the same, multiply by 1000 to give me metres per hour per hour then divide by seconds in an hour squared??
