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.

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: 299,792,458 m/s (meters/second)
• 1 week = 7 days = 168 hours = 10080 minutes = 604800 seconds
• 1 light week = 181,314,478,598,400 m = 1.8131448 * 10¹⁴m

Comparison to other Units

• 1 light week = 181,314,478,598.400 km = 1.8131448 * 10¹¹ km
• 1 light week = 112,663,593,736.578 mi = 1.1266359 * 10¹¹ mi
• 1 light week = 594,863,774,929,133.858 ft = 5.9486377 * 10¹⁴ ft
• 1 light week = 198,287,924,976,377.952 yd = 1.9828611 * 10¹⁴ yd

Distances in Light weeks

Unfortunately there are no distances in nature where it make sense to express them in light weeks. Distances in our solar system are normally expressed in light seconds up to light days. Distances in our galaxy are normally expressed in light years.
