38) True. They are exactly the same size. Syringes are generally calibrated in either cc's or ml's. Heaven help the nurse who doesn't know they're the same. He's potentially going to kill someone.

According to A Dictionary of Units by Frank Tapson: "When the metric system was introduced in the 1790's the litre was intended to match up with the volume occupied by 1 kilogram of pure water at a specified pressure and temperature. As the ability to measure things got better (by 100 years later) they found that there was a mismatch between the kilogram and the litre. As a result of this they had to redefine the litre (in 1901) as being 1.000028 cubic decimetres. Very handy! This nonsense was stopped in 1964 when it was ruled that the word "litre" may be employed as a special name for the cubic decimetre..."

Note that 1 cubic decimetre = 1000 cm3. In other words 1 ml = 1 cm3.
