Why do you suppose the united states still uses the english system for everyday measurements while almost every other country us
Alchen [17]
Answer:
Because the English measurement system has been in use for a very long time, it will be costly and time consuming to change from the English to SI units. Many technological measurements, products, and tools were developed in English units.

The cost of converting all measurements to SI units will be costly and will require a long period of time. Conversions between the English and the SI system of units appear to be more cost-effective than hardware changes.

Example:
It will be costly to convert designs for bridges, tunnels, locomotives, automobiles, and other hardware to the SI system. Although new designs are being performed in SI units, much useful hardware based on English units still remain.

Eventually, it is likely that complete conversion from English to SI units will happen, albeit slowly.

Amiraneli [1.4K]

According to the question, the amount of the drug administered is 250 milligram (mg). The available dose of the drug is 250 mg per 1.5 mL (milligram). So, for the administration of the 250 mg drug, 1.5 mL of the available drug concentration should be used.

We need to determine the amount of the drug must be drawn in cc (cubic centimeter).

1mL = 1cc

As

1.5 mL = 1.5 cc

So, the amount to be drawn is 1.5 cc.
