将 米 转换为 地球赤道半径
米
定义: A meter, or metre (symbol: m), is the base unit of length and distance in the International System of Units (SI). The meter is defined as the distance traveled by light in 1/299 792 458 of a second. This definition was slightly modified in 2019 to reflect changes in the definition of the second.
历史/来源: Originally, in 1793, the meter was defined as one ten-millionth of the distance from the equator to the North Pole. This changed in 1889, when the International prototype metre was established as the length of a prototype meter bar (made of an alloy of 90% platinum and 10% iridium) measured at the melting point of ice. In 1960, the meter was again redefined, this time in terms of a certain number of wavelengths of a certain emission line of krypton-86. The current definition of the meter is effectively the same as the definition that was adopted in 1983, with slight modifications due to the change in definition of the second.
当前使用: Being the SI unit of length, the meter is used worldwide in many applications such as measuring distance, height, length, width, etc. The United States is one notable exception in that it largely uses US customary units such as yards, inches, feet, and miles instead of meters in everyday use.

| 0.10 m | 0.000000 radius |
| 1 m | 0.000000 radius |
| 2 m | 0.000000 radius |
| 3 m | 0.000000 radius |
| 5 m | 0.000001 radius |
| 10 m | 0.000002 radius |
| 20 m | 0.000003 radius |
| 50 m | 0.000008 radius |
| 100 m | 0.000016 radius |
| 1000 m | 0.000157 radius |
如何将 米 转换为 地球赤道半径
1 m = 0.000000 radius
1 radius = 6378160 m
示例
Convert 15 m to radius:
15 m = 15 × 0.000000 radius = 0.000002 radius
