The athenosphere.
The exosphere is the outer layer of the atmosphere. It goes from about 400 miles (640 km) high to about 800 miles (1,280 km). The lower edge of the exosphere is where atmospheric pressure and temperature is very low (the gas atoms are very widely spaced).
The Great Red Spot is about 24,000-40,000 kilometers by 12,000 to 14,000 kilometers. It is between 300 to 400 years old.
The Space Shuttle orbited at an altitude of around 185 kilometers (115 miles) to 643 kilometers (400 miles) above Earth's surface.
The International Space Station orbits Earth at an average distance of about 250 miles (400 kilometers) from the Earth's surface. The Earth is approximately 93 million miles (150 million kilometers) away from the Sun. Therefore, the International Space Station is about 93 million miles (149.6 million kilometers) plus 250 miles (400 kilometers) away from the Sun.
The International Space Station orbits Earth at an average altitude of about 250 miles (400 kilometers).
To determine the number of thousands in 400 tens, we first need to convert 400 tens to its equivalent in hundreds, which is 40 hundreds. Then, we convert 40 hundreds to its equivalent in thousands, which is 4 thousands. Therefore, there are 4 thousands in 400 tens.
There are 40,000,000 centimeters in 400 kilometers, as there are 100,000 centimeters in a kilometer.
400.
There are 400 thousands in 400,000 because 400,000 divided by 1,000 equals 400. Therefore, when you express 400,000 in terms of thousands, it is equal to 400 thousand.
For practical purposes 8 kilometers = 5 miles. Therefore 400 kilometers = 400 x 5/8 = 250 miles.
400 nanometers = 4.0 × 10-10 kilometers
1 mile = 1.609344 kilometers 400 million miles = (400 million x 1.609344) = 643.7376 million kilometers = 643,737,600kilometers (rounded)
400 meters is 0.4km
You cannot convert 400 meters to 3 kilometers. They are two different lengths. 1 kilometer = 1,000 meters. 3 kilometers would be 3,000 meters. 400 meters would be 0.4 kilometers
400 miles + 400 km = 648.548 miles or 1,043.736 km.
400 kilometers ≈ 248.548477 mi
400 kilometers = 248.55 miles.
