Weeks to Microseconds (wk to µs)
1 week equals 604,800,000,000 microseconds exactly.
How to convert weeks to microseconds
To convert weeks to microseconds, multiply the number of weeks by 604,800,000,000. This factor is exact. To go the other way, multiply microseconds by 1.653439153×10⁻¹² (rounded).
microseconds = weeks × 604,800,000,000
Example: 10 weeks = 6,048,000,000,000 microseconds.
Months and years are not constant. This site uses the average Gregorian year of 365.2425 days, so one 'year' converts to 365.2425 days, not 365; use 'common year' for exactly 365 days.
About these units
Week (wk)
Seven days. The seven-day week comes from the ancient Near East and is nearly universal in the modern calendar.
Nothing in the sky produces a seven-day cycle, which makes the week a human invention with a contested pedigree. Babylonians marked the 7th, 14th, 21st and 28th of the lunar month as special, but that was not a continuous cycle. A continuous seven-day cycle tied to the Sabbath is attested in Judaism by the 6th century BC at the latest, and scholars disagree on whether it was borrowed from Babylon or developed independently. The Romans later used a week named for the Sun, the Moon and the five visible planets, and in AD 321 Emperor Constantine decreed it across the empire.
A week is seven days, or 604,800 seconds, and it divides evenly into neither months nor years, which is why calendars shift against it. The ISO 8601 standard starts each week on Monday and assigns week 1 to the week containing the year's first Thursday, so some years have a week 53. Other societies used different lengths: Rome had an eight-day market cycle, and revolutionary France used a ten-day week from 1793 to 1802. The English word comes from Old English wice, meaning a turn or succession.
1 week = 604,800 seconds (exactly).

Microsecond (µs)
One millionth of a second. Used for electronics and processor timing.
Writing a microsecond takes a Greek letter, mu, which stands for the prefix micro-, one millionth. Where plain text cannot display it, people fall back on the letter u and write us. The unit belongs to electronics and radio: a signal that repeats every microsecond has a frequency of 1 MHz, and a radio wave of that period is about 300 m long.
A microsecond is one millionth of a second, short enough that light in a vacuum crosses only about 1 km in 3.34 of them. Digital audio lives on this scale, because a CD sample at 44.1 kHz lasts about 22.7 microseconds and a 48 kHz sample about 20.8. A modern solid-state drive has an access latency of about 50 microseconds, and a camera flash lasts around 1,000. Relativity matters at this scale too: GPS satellite clocks would drift by about 38 microseconds per day without compensation. Wikipedia notes that the 2011 Japanese earthquake shortened the day by about 1.8 microseconds.
1 microsecond = 0.000001 seconds (exactly).
