Converting C to F
Problem: It is not uncommon to find degrees Centigrade used in technical literature and articles. However, you really want to know what that Centigrade number is in degrees Fahrenheit.
Problem: It is not uncommon to find degrees Centigrade used in technical literature and articles. However, you really want to know what that Centigrade number is in degrees Fahrenheit. Is there an easy way to make this conversion without having to deal with that 5/9 or 9/5 formula?
Solution: The calculation can be made quickly and easily, probably without using paper and pencil. Multiply degrees C by 2 and then move the decimal point of the result one place to the left. Subtract this number from the original calculated figure and add 32 to get F.
For example, assume you want to convert 50.5 C to F. Multiplying by 2 yields 101. Moving the decimal point left converts this number to 10.1. Subtracting 10.1 from 101 equals 90.9. Adding the 32 makes 50.5 C equal to 122.9 F.

Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.
There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.
But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
