Use this simple rule for CONVERTING INCHES into CENTIMETERS when you put the words of H. Jackson Brown on the wall and you need to get a special poster frame.

Converting inches to centimeters takes a simple mental trick.  You can use a table (below) or use the "parts" and figure out the result.

For example, 11 by 35 is really   (12-1) by (36-1)

We know that 1 inches is 2.5 cm
12 inches is 30.5 cm

So 30.5 - 2.5 = 28 cm or 11 inches
91.5 - 2.5 = 89 CM or 35 inches.

We are especially attracted to the words of H. Jackson Brown (whose advice might connect with some teenagers).

Then we needed to get a FRAME that would display the poster.   The size, 11 by 35, is unusual.

RULE for converting INCHES into CENTIMETERS.
You can remember 12 inches is 30 CM or 2 inches is 5 cm or 1 inch is 2.54 cm.



You can also use the following table... but the "subtraction or addition" method is a fun way to use algebra.
