Water covers 71% of the Earth's surface. It is impossible to tell exactly how much water is on Earth due primarily to the vast size of the Earth and also the amount of water in the air in the form of water vapor.Otherwise, the collective mass of water found on, under, and over the surface of a planet is called the hydrosphere. Earth's approximate water volume (the total water supply of the world) is 1 360 000 000 km³ (326 000 000 mi³ or 3.59×1020 US gallons). Of this volume:1 320 000 000 km³ (316 900 000 mi³ or 97.2%) is in the oceans.25 000 000 km³ (6 000 000 mi³ or 1.8%) is in glaciers, ice caps and ice sheets.13 000 000 km³ (3 000 000 mi³ or 0.9%) is groundwater.250 000 km³ (60 000 mi³ or 0.02%) is fresh water in lakes, inland seas, and rivers.13 000 km³ (3 100 mi³ or 0.001%) is atmospheric water vapor at any given time.--Wikipedia, (2009?)
Answer: 5,676,480,000,000 mi. = 9,135,409,029,120 km
1 320 000 000 km³ (316 900 000 mi³ or 97.2%) of the total.
45,000 miles = 72,420.5 kilometres, approx. The formula for converting miles to km 45,000 mi* 63360 in 1 mi * 2.54 cm 1 in * 1 km 100000 cm = 72,420.48 km
