The formulas for conversion are represented below:
pc = mm / 3,086x1019
Example: 30 Millimeters in Parsecs:
pc = mm / 3,086x1019
pc = 30 / 3,086x1019
pc = 9.7223x10-19
mm = pc * 3,086x1019
Example: 1.5 Parsecs in Millimeters:
mm = pc * 3.086x1019
mm = 1.5 * 3.086x1019
mm = 4.629x1019
Considering that 1 Millimeter is equivalent to 3,241x10-20 Parsecs, you can use a rule of three to get that 100 Millimeters equals 3,241x10-18 Parsecs.
1 mm - 3,241x10-20 pc
100 mm - x
Apply the rule of three and get:
x mm = 100 * 3.241x10-20 pcmm
x = 3.241x10-18 pc
If every 1 Parsecs we have 3,086x1019 Millimeters, just multiply the amount of Parsecs (100) by 3,086x1019, so you will get 100 pc are equivalent to 3.086x1021 mm. Observe the calculation below:
mm = pc * 3.086x1019
mm = 100 * 3.086x1019
mm = 3.086x1021
