Why might using speed of light to determine the length of the meter be more reliable than using a measured distance around earth?

The speed of light in vacuum is a universal constant. The distance around the earth depends on the line of measurement. Because of its rotation, the earth is not a perfect sphere: its equatorial radius is 0.3% greater than its polar radius. Consequently the measurement is affected by the exact line along which the radius is measured.
Furthermore, there are two kinds of variations in the equatorial radius. One is a long-term variation caused by the distribution of mass on the surface: possibly the ocean mass. There is also the short term variation caused by the gravitational pull of the moon.

Why is distance around the equator measured at 24783mi when the distance around the earth is measured at 24901 mi?
The earth is slightly wider than it is tall, so the measurement around the equator is going to be a just over a hundred miles greater than the distance around the earth.
What is the unit used to measure distances around a circle?
The distance around a circle is its circumference and it can be measured in any linear units.
What is the unit of metric distance?
If you define 'distance' as the shortest line between to objects. (Example: the moon and the Earth; or say, Suburb A and Suburb B, then such distances are measured in Metre if the distance is shorter than around about 1 Kilometre, or,. If the distance is greater than a few hundred Metre, it is always measured in Kilometre.
Is used to measure distance in the solar system is?
Inside our Solar System distances are measured in Astronomical Units (AU) which is the average distance from the Earth to the Sun, or about 93 million miles. Jupiter is about 5.5 AU distance from the sun or around 500 million miles. Distances outside our Solar System are usually measured in Light Years.
How is a sandstorm forecasted or detected?
Sandstorms can be detected and measured with the meteorological tools. They use radars, sightings, and can determine just how the weather around them are exceeding to a SEVERE WEATHER. This can cause destruction to the human society etc.

How can I determine the distance around a circle if I know the distance across the circle?
The diameter times Pi gives you the circumference.
What is the unit used to measure distances around a circle?
The distance around a circle is its circumference and it can be measured in any linear units.
What is the distance measured around a circle?
It's called the "circumference" of the circle. It's equal to (pi) times (the circle's diameter).
Why do we measure circumference?
The circumference is the distance around a circle and it is measured by:- Circumference of a circle = 2*pi*radius or pi*diameter
Is circumference measured in cm?
Circumference can be measured in any linear measurement. It could be centimeters, meters, miles, inches etc. generally the circumference is the linear distance around a circle. When you have a perfect circle, it's fairly easy to calculate if you know the distance across the circle.
What is the distance around an official Olympics running track?
The Olympics uses a track of 400 meters in length, as measured in lane 1.
What is a five letter word ending in H meaning distance around a person's body?
The answer is girth.It's five letters, ending in H. The girth refers to the measured distance around an person's body.

Why might using the speed of light to determine the length of the meter be more reliable than using a measured distance around Earth?
Because the speed of light is constant at 186,282 miles (or 299,792,458 metres) per second). The Earth, although appearing to be solid - actually 'flexes' due to the molten inner core and gravitational pull of the Sun (and to some extent the moon). Additionally, the surface is not uniformly flat - this would mean measuring a 'standar' metre would be subject to errors (albeit minute).
How reliable is shipment tracking and what is the technology used for tracking shipments all around the globe?
Shipment tracking is fairly reliable, but susceptible to human error. Tracking works by scanning shipments at terminal points and using GPS to determine the location of invididual trucks.
