## Pipe Diameter Tape Measures Are Made For All Users

The United States never did switch over to the metric system, as it was planned in the 1960’s and 1970’s. Yes, metric went over like a lead balloon. Americans are happy with inches, feet, gallons, and yards. The centimeter, liter and meter were mostly rejected. Both systems are used today in 2021 in labeling food products and liquids, but we Americans have learned to skim over those parts of the label that don’t fit into our familiar system.

The scientific community is firmly based on the MKS and CGS systems (meter, kilogram, second) and (centimeter, gram, second). The biggest part of the world is metric-based also.

Fortunately, pipe diameter tape measures are made for both systems, separately, and there is even one that is made with the inch and metric system together. The front side of the tape is in diameter inches (up to 38). The back side is in diameter millimeters (up to 955). This is a rare tool, but some companies need both measurements to satisfy their requirements.

## Using a Pipe Diameter Tape Measure Is a No-Brainer

If you have a pipeline and need to find the OD (outside diameter) it makes sense to use a pipe diameter tape measure. Even a chimp could be trained to use one. (I think). All you do is

1. Wrap the tape around the pipe.
2. Read the marking where the zero mark touches the tape.
3. Even though the tape is wrapped around the circumference, it is marked by a factor of pi, so it gives you the diameter.
4. You’re done.

Now it’s time to enjoy the rest of the day in the shade.

## The Anatomy of Today’s Architect Scale Ruler

An architect scale ruler is used by architects, designers, planners, and draftsmen. If you are going to order some with your company logo, which ruler should you choose?

• 6 inches long, or 12 inches long? Will the person using it, be carrying it in their shirt pocket, or in their brief case, or on their desk?
• Scales. A good architect scale ruler has at least 8 scales. Examples are (1/8, ¼), (½, 1), (3/8, 3/4), (3, 1½). These are listed in pairs, because they share the same edge, but are marked in opposite directions.
• Color. It is good to choose a color that goes with your corporate colors.
• Imprint color. The logo imprint color is usually the same color as the markings. So, you should choose a markings color that has a high contrast from the color of the ruler.
• A good ruler is imprinted using a photo anodized method. This assures smooth edges, so you can use a pen or pencil to draw tick-free lines.
• Aluminum is the best material, since it doesn’t warp.

If your architect ruler has all these characteristics, you have a good one.
