The inch is now measured in 2.54 cm.
The distance between the countries can be find by travelling
Frequency is no longer measured in cycles per second. It is now measured using the unit 'hertz' (abbreviation Hz). However, one hertz is exactly the same thing as one cycle per second.
That's the unit of frequency ... "cycles per second", or simply "cycles".It has now been officially renamed the "Hertz".
yes it is we are learning this now and the answer is yes(:
Distances within the solar system are expressed in terms of the distance between the Earth ans the Sun. This distance is called an astronomical unit (abbreviated as au), a unit of length now defined as exactly 149,597,870,700 meters or 92,955,807.3 miles).
Traditionlly, soccer fields are measured in yards. Since most of the world now uses the metric system, the official rules now measure in meters. For example, the required distance for opponents to stand is now 9.15 meters, instead of the traditional 10 yards. Measurements in feet are still traditionally used for the height of a goal structure's crossbar, but this too is officially measured in the metric system.
Any unit of distance can be used to describe any distance.In the case of the stars, the nearest one to our solar system is about 4.3 light yearsaway, or about 25,261,000,000,000 miles.That's the nearest star, after the sun.Can you see now why most astronomers choose to talk about light yearsrather than miles.
Curie (Ci) is the old unit of radioactivity; now is used in SI the becquerel. The correct word is decays not emissions. 1 curie = 3,7.1010 decays/second
The wind direction is measured with wind vanes or wind socks. Sexagesimal degrees.
On the surface of the Earth, miles used to be the traditional measure, but now displaced by the SI system with kilometres. An exception is in aviation, where horizontal distances are still measured in miles, and altitude measured in thousands of feet. This is to avoid confusing numbers between these two dimensions. There will still be many ships which measure speed in knots, and distance in nautical miles.
