  2. Metric System vs. Standard System - Physics Forums

    www.physicsforums.com/threads/metric-system-vs-standard...

    Thats the only system we've ever used in my high school science classes (I live in the US). Only some "regular" class people and non-science/math oriented people don't know the metric system in my school. Only problem is that I can work out a problem in the metric system but it's hard for me to relate metric measurements in the real world.

  3. Metric System vs. Standard System | Page 2 - Physics Forums

    Being a base 10 system makes the metric system easier to use, but the biggest advantage is correlation between different units of measure. It's easy to convert cubic centimeters to milliliters to liters, volume to mass, etc.

  4. English vs Metric Units: Pros and Cons - Physics Forums

    www.physicsforums.com/threads/english-vs-metric-units-pros...

    Most countries have adopted the metric system as their standard system of measurement, making it the most widely used system in the world. What are the advantages of using Metric units? One of the main advantages of using Metric units is that it is a decimal-based system, making conversions between units much easier.

  5. What are the meanings of cm^2 and cm^3 in the metric system?

    www.physicsforums.com/threads/what-are-the-meanings-of-cm...

    FAQ: What are the meanings of cm^2 and cm^3 in the metric system? What is the difference between cm^2 and cm^3? cm^2 and cm^3 are both units of measurement used to describe volume. However, cm^2 refers to square centimeters, which is a unit of area, while cm^3 refers to cubic centimeters, which is a unit of volume. How do you convert cm^2 to cm^3?

  6. Metric VS English engineering system of measurement

    www.physicsforums.com/threads/metric-vs-english...

    In summary, some people in the US want to switch to the metric system because it is more accurate. However, the system has been in place since 1866 and is already present in various forms. There are also some difficulties with transitioning to the metric system, such as the fact that many things are labeled in both metric and English.

  7. Is there any difference between Metric, Metric Tensor, Distance...

    Thanks, DrGreg. Now, the correct text. Difference between the metric and the metric tensor. 1) Metric: is a quadratic relationship involving the squares of the differences between the coordinates of two nearby points in space-time, which allows calculating the geometrical properties of spacetime, as distances (or intervals between events) and angles between neighboring points.

  8. Are Metric and Imperial Bolts Interchangeable? - Physics Forums

    www.physicsforums.com/threads/are-metric-and-imperial...

    Metric bolts are measured in millimeters and use the metric system of measurement, while imperial bolts are measured in inches and use the imperial system of measurement. 2. Can metric bolts be used interchangeably with imperial bolts? No, metric and imperial bolts have different thread sizes and pitches, so they are not interchangeable. 3.

  9. Metric: Proper Space vs Coordinate Space - Physics Forums

    www.physicsforums.com/threads/metric-proper-space-vs...

    So the proper length between them will be affected by the metric. b) Consider a light path. Suppose a beam propagates along z axis in the coordinate space. Then it will remain on it. However, due to the gravitational field, the projection of z axis to the proper system may be a curve, so the light actually travel along a curve.

  10. Memorizing Metric Prefixes: Tips & Tricks - Physics Forums

    www.physicsforums.com/threads/memorizing-metric-prefixes...

    In summary, metric prefixes are standard abbreviations used in the metric system to represent different units of measurement. It is important to memorize them in order to easily convert between units and accurately communicate results. Some tips for memorizing include using mnemonic devices and understanding the pattern of each prefix.

  11. What Do Lbf, Lb, and Lbm Really Mean in American Units? - Physics...

    www.physicsforums.com/threads/what-do-lbf-lb-and-lbm...

    1 lb f is the unit of force employed in american system. 1 lb f is equal to the force exerted by gravity on 1 lb m at the Earth's surface. There is an equation for getting the net force F (lb f) on an object of mass m (lb m) when it experiences an acceleration a (ft/s 2). This is the american system version of Newton's second law: [tex]F=m ...
