Metric Rebars
You may not realize it, but virtually all the reinforcing bar currently produced in the United States is a “soft metric” bar. This not-so-well-known fact conjures up several important questions: Is there a difference in size between a soft metric rebar and an inch-pound rebar? What about the design strengths of reinforcing steel with soft metric and inch-pound units of measure? More importantly, do your employees understand that there is no physical difference between a #3 inch-pound rebar and a #10 soft metric rebar?

Metric Electrical Conduit Size
The electrical conduit is a vital part of any wiring effort. To get it right, you need to understand metric electrical conduit size options. Electrical conduit refers to the tubing that contains electrical cable and wiring. Conduit serves a variety of purpose. It keeps the electrical cable contained and orderly. It protects the cables and provides fire protection where the cables pass through walls.

Speeding, traffic signs and metric
In 1865, the revised Locomotive Act reduced the speed limit to 4 mph (6 km/h) in the country and 2 mph (3 km/h) in towns. The 1865 Act required a man with a red flag or lantern to walk 60 yards (50 m) ahead of each vehicle, enforce a walking pace, and warn horse riders and horse drawn traffic of the approach of a self-propelled machine. The replacement of the “Red Flag Act” by the Locomotive Act of 1896, and the increase of the speed limit to 14 mph (23 km/h) has been commemorated each year since 1927 by the London to Brighton Veteran Car Run.Nepal, the Isle of Man and the Indian states of Uttar Pradesh and Kerala are the only places in the world that do not have a general speed limit.
