A gry is an old English measure for length, defined as 1/10 of a line, where line is another old English measure for length, defined as 1/12 inch. A common measure for length in the publishing business is a point, defined as 1/72 inch. What is an area of 0.42 gry2 in points squared?
To determine the area of 0.42 gry² in points squared, we need to convert the gry² measurement to points squared.
First, let's convert gry to inches. Since 1 gry is defined as 1/10 of a line, and 1 line is defined as 1/12 inch, we can calculate:
1 gry = (1/10) * (1/12) inch = 1/120 inch
Next, to convert gry² to square inches, we square the gry measurement:
(1/120 inch)² = 1/14400 square inches
Finally, let's convert the square inches to points squared. Since 1 point is defined as 1/72 inch, we can calculate:
(1/14400 square inches) * (1/72 inch/point) * (1/72 inch/point)
= (1/14400) * (1/5184) points squared
= 1/7,516,800 points squared
Therefore, the area of 0.42 gry² is approximately 1/7,516,800 points squared.
