Why the US clings to inches and pounds while the world goes metric: Key differences between imperial and metric systems explained
People In striking contrast to the ethnic and racial diversity that characterize large American cities, Tokyo, like the rest of Japan, is overwhelmingly mono-racial.
People With a population of 9.9 million people in the central city, Mumbai is the third-largest city in the world. Some 15.4 million live in Greater Mumbai (Mumbai and its suburbs). Though much of the city's population are Marathas, inhabitants of Maharashtra and speaking the Marathi language, Mumbai is a cosmopolitan city.
People Thailand is one of the most racially homogenous countries in Asia, with more than 80 percent of its population being native Thai.
People Johannesburg is a multicultural and multiethnic city. Racially, its population is approximately 70 percent black and 25 percent white, with the remainder Indian or of mixed racial background. However, there is great diversity within each racial group.
People During most of the twentieth century, Rio de Janeiro grew rapidly, mostly with Brazilian migrants from the states of Rio de Janeiro, Minas Gerais, and Espírito Santo. Growth began to level off in 1960 when Rio lost its status as the nation's capital.

One such case is versus, which is often written in a shortened form. You may choose between vs, vs., and v. Take care, when writing the word out in full, that you distinguish between versus (a preposition meaning “against”) and verses (“lines of metrical writing”).
A metric ISO screw thread is designated by the letter M followed by the value of the nominal diameter D (the maximum thread diameter) and the pitch P, both expressed in millimetres and separated by a dash or sometimes the multiplication sign, × (e.g. M8-1.25 or M8×1.25).
A standard that describes the shape of an internal or external thread using metric millimeter dimensions. Making a thread that follow these specifications will ensure that it will work with threaded holes and shafts made by other manufacturers that follow these common specifications.
The ISO metric screw threads are the world-wide most commonly used type of general-purpose screw thread. They were one of the first international standards agreed when the International Organization for Standardization was set up in 1947.
In October 2023 the biggest revision of ISO 68-1 in 50 years was released. This standard defines the profile, or shape, of the metric thread. It is referenced by any metric thread fastener standard.

The metric M profile threads of tolerance class 6H/6g are intended for metric applications where the inch class 2A/2B have been used. At the minimum material limits, the 6H/6g results in a looser fit than the 2A/2B.
The design principles of ISO general-purpose metric screw threads ("M" series threads) are defined in international standard ISO 68-1. Each thread is characterized by its major diameter and its pitch.
Our engineers can help you design custom thread profiles for high-stress applications or unique material requirements. Get basic dimensions for metric threads including major and pitch diameters. Use standard ISO specs for internal and external components.
This first edition, together with ISO 68-2, cancels and replaces ISO 68:1973 which has been technically revised by separating the metric dimensions from the imperial dimensions.
ISO metric threads are similar to the Unified Thread Standard (UTS) threads mostly used in North America (UNC and UNF), as both feature a 60° V profile. The key difference is that UTS is inch-based while ISO is metric-based, resulting in different measuring systems and non interchangeable parts.
Consumer Reports: What is the difference between P-Metric and Metric tire sizing?
In our Tire Talk forum, some of our readers have questioned the interchangeability of P-metric and Metric tire size designations. But answering this question is like asking how to solve the national ...
