Light week

The light week is the distance that the light travels in vacuum in one week and so is a unit of distance.

Similar units are the light second, light minute, light hour, light day, light month, light year. A light minute is 60 light seconds and a light hour is 60 light minutes, or 3600 light seconds.

numerical value

As opposed to the light year, whose value more or less depends on the definition of year, the value of the light hour is defined exactly.

• velocity of light in vacuum: 2.99792456 * 10⁸ m/s (meters/second)
• 1 [[week] = 7 days = 168 hours = 10080 minutes = 604800 seconds
• 1 light day = 1.8131446 * 10¹⁴m

Comparison to other Units

• 1 light week = 2.8231447 * 10¹¹ km
• 1 light week = 1.1266359 * 10¹¹ mi
• 1 light week = 1.6028637 * 10¹⁵ ft
• 1 light week = 1.9828611 * 10¹⁴ yd
