How many miles is 2 degrees longitude?
Each degree of latitude is approximately 69 miles (111 kilometers) apart.
How many degrees are in a mile?
Each degree of latitude is approximately 69 miles (111 kilometers) apart. The range varies (due to the earth's slightly ellipsoid shape) from 68.703 miles (110.567 km) at the equator to 69.407 (111.699 km) at the poles. This is convenient because each minute (1/60th of a degree) is approximately one (nautical) mile.
How many miles is 1 degree longitude at the equator?
60 geographical miles A geographical mile is defined to be the length of one minute of arc along the equator (one equatorial minute of longitude) therefore a degree of longitude along the equator is exactly 60 geographical miles or 111.3 kilometers, as there are 60 minutes in a degree.
How many nautical miles are in 1 degree of longitude?
60 nautical miles mile or 1 nm, equivalent to 1.582 km), so one degree (1°) of latitude corresponds to 60 nautical miles or approximately 111 km. The length of one degree (1°) of longitude varies because the meridians converge towards the poles. At the equator one degree of longitude is nearly the same as one degree of latitude (60 nm).
How do you convert latitude to miles?
As such, it is easy to convert latitude into miles. Divide the amount of miles by the degrees in a circle. The circumference of the earth along the equator is 24,901.92 miles, and there are 360 degrees in a circle. This results in about 69.2 miles.
How do you calculate degrees of longitude?
The Earth rotates one full turn (360º of longitude) in one day. It therefore turns one degree of longitude in 1/360th of a day, or every four minutes. To calculate your longitude, you therefore simply need to work out the time difference between noon at your location and noon at the Prime Meridian.
How many meters is a degree of longitude?
How Far Is One Degree? Converting NASA's measurement of the Earth's radius into meters and substituting it in the formula for arc length, we find that each degree the radius line of the Earth sweeps out corresponds to 111,139 meters.
How many miles is 360 degrees?
The circumference of the earth along the equator is 24,901.92 miles, and there are 360 degrees in a circle. This results in about 69.2 miles. That is the approximate distance between each degree of latitude.
What is the distance between two longitudes called?
Yes, the distance between two longitude lines is called gore. A gore is the curved surface which lies between two close lines of longitude on a globe. It refers to a sector of a curved surface. It is possible to flatten it to a plane surface with little distortion.
How do you convert latitude and longitude to distance?
For this divide the values of longitude and latitude of both the points by 180/pi. The value of pi is 22/7. The value of 180/pi is approximately 57.29577951. If we want to calculate the distance between two places in miles, use the value 3, 963, which is the radius of Earth.
How do you find the distance between two lines of longitude?
As a general rule, the formula for the distance between meridians is therefore (2πR)(cos L), where L is latitude and R is the radius of the Earth.
How do you calculate longitudinal distance?
The approximation for 1 degree of longitude = cos(Latitude)*degree length of longitude at the equator. Hence, the latitude of a point d kilometres away will be: Using these equations, we can generate four new points surrounding the original.
How much meters are in a mile?
1,609.344 meters How many meters in a mile 1 mile is equal to 1,609.344 meters, which is the conversion factor from miles to meters.
How far is 0.001 longitude?
111 meters So, at the Equator, 0.001∘ of longitude will also be 111 meters.
Why is a nautical mile different to a land mile?
Nautical miles are used to measure the distance traveled through the water. A nautical mile is slightly longer than a mile on land, equaling 1.1508 land-measured (or statute) miles. The nautical mile is based on the Earth's longitude and latitude coordinates, with one nautical mile equaling one minute of latitude.
How do you calculate distance using latitude and longitude?
φ is latitude, λ is longitude, R is earth's radius (mean radius = 6,371km);…Spherical Law of Cosines.
| Law of cosines: | d = acos( sin φ1 ⋅ sin φ2 + cos φ1 ⋅ cos φ2 ⋅ cos Δλ ) ⋅ R |
|---|---|
| Excel: | =ACOS( SIN(lat1)*SIN(lat2) + COS(lat1)*COS(lat2)*COS(lon2-lon1) ) * 6371000 |
Where is 180 degrees longitude?
The international date line, established in 1884, passes through the mid-Pacific Ocean and roughly follows a 180 degrees longitude north-south line on the Earth. It is located halfway around the world from the prime meridian — the 0 degrees longitude line in Greenwich, England.
What is the distance per degree of latitude?
The distance of each degree of latitude is approximately 111 km.
How do you calculate degrees of latitude and longitude?
The approximation for 1 degree of longitude = cos(Latitude)*degree length of longitude at the equator. Hence, the latitude of a point d kilometres away will be: Using these equations, we can generate four new points surrounding the original.
What makes up a mile?
mile, any of various units of distance, such as the statute mile of 5,280 feet (1.609 km). It originated from the Roman mille passus, or “thousand paces,” which measured 5,000 Roman feet. About the year 1500 the “old London” mile was defined as eight furlongs.
Which is longer a meter or a mile?
There are 1609.344 meters (m) in 1 mile. A meter, or metre, is the base unit of length in the International System of Units (SI). A mile is a measurement of length in the US customary and imperial systems of measurement.
What is the equivalent of 0.5 degree of latitude?
about 55km Since one degree (1°) near the equator is equivalent to about 111 km, either moving to south or north poles of both the longitude and the latitude, though slight difference of about 1km. Therefore, 0.25° by 0.25° gridded degree is equivalent to about 27.75 km, while 0.5° by 0.5° is about 55km.

Why do boats use knots instead of mph?
Cars and trains, known for shorter travel segments, use miles per hour or kilometers per hour. Boats and planes, which often travel longer distances affected by the earth's curvature, use knots. Knots are a more accurate way of predicting how a boat (or a plane) traverses the face of the earth.
What is 40 knots in miles?
Now we know that 40 knots are equal to 46.03 mph.
How do you calculate distance in miles?
See shortcuts for time formats below. To solve for distance use the formula for distance d = st, or distance equals speed times time. Rate and speed are similar since they both represent some distance per unit time like miles per hour or kilometers per hour. If rate r is the same as speed s, r = s = d/t.
How do you convert latitude to distance?

What is 0 longitude called?
The prime meridian is the line of 0° longitude, the starting point for measuring distance both east and west around the Earth. The prime meridian is arbitrary, meaning it could be chosen to be anywhere. 6 – 12+ Earth Science, Geography.
Why is Greenwich 0 degrees longitude?
The line in Greenwich represents the historic Prime Meridian of the World – Longitude 0º. Every place on Earth was measured in terms of its distance east or west from this line. The line itself divided the eastern and western hemispheres of the Earth – just as the Equator divides the northern and southern hemispheres.
What is longitudinal distance?
Longitude is measured by imaginary lines that run around the Earth vertically (up and down) and meet at the North and South Poles. These lines are known as meridians. Each meridian measures one arcdegree of longitude. The distance around the Earth measures 360 degrees.
