1 Which gives us an answer of 0.010869565cm3.  The final step is to convert your volume into ml. As 1cm3 = 1ml it's a 1:1 conversion. So, we don't need to do anything and therefore have our answer. 10mg of sunflower oil is 0.010869565 ml.
No. When a child reaches age 8 (regardless of weight) OR reaches 80 pounds (regardless of age), a properly fitted seat belt may be used instead of a child restraint/booster to restrain the child. However, keep in mind that the seatbelt may not fit properly even if the child is 8 years old or weighs 80 pounds. The law does require that children stay in a child restraint or booster seat until the seat belt fits properly on its own.
Some go into the booster seat before they r 2 yrs old. Now the law is enforcing that kids be in booster seat til they turn 8 yrs old. Mine has long legs so I had to switch them around 15 or 16 months old.They weighed over 30 lbs too. Going by what your child can do is alot safer than going by age. If your child can sit without support, and hold his own head up, and is at least 24 pounds ( a little less is okay.) Then is is probably okay to put him in a booster seat.
