How many grams are in 1.48 x 10^7 micrograms

1.       How many grams are there in 1.48 x 10^7 mcg
Before we were able to identify how many grams are there in the given mcg measure, let us solve first the given equation
=> 1.48 x 10^7, multiply first 10 7 times.
=> 1.48 x (10 x 10 x 10 x 10 x 10 x 10 x 10)
=> 1.48 x 10 000 000
=>  14 800 000 micrograms
How many micrograms are there in 1 gram
=> 1 grams = 1 000 000 micrograms
Thus, we need to divide 14 800 000 / 1 000 000
=> 14.8 grams
