Weeks, months, and years are significantly variable units whose length depend on the choice of calendar and are often not regular even with a calendar, e.g., leap years versus regular years in the Gregorian calendar. For everyday use and most other scientific contexts, the common units of minutes, hours (3,600 s or 3.6 ks), days (86,400 s), weeks, months, and years (of which there are a number of variations) are commonly used. Metric units of time larger than the second are most commonly seen only in a few scientific contexts such as observational astronomy and materials science, although this depends on the author. Metric prefixes are defined spanning 10 −30 to 10 30, 60 decimal orders of magnitude which may be used in conjunction with the metric base unit of second. Those amounts of time together span 60 decimal orders of magnitude. The largest realized amount of time, based on known scientific data, is the age of the universe, about 13.8 billion years-the time since the Big Bang as measured in the cosmic microwave background rest frame. The smallest meaningful increment of time is the Planck time―the time light takes to traverse the Planck distance, many decimal orders of magnitude smaller than a second. Clock time and calendar time have duodecimal or sexagesimal orders of magnitude rather than decimal, e.g., a year is 12 months, and a minute is 60 seconds. Therefore, it is said "a million years" instead of "a mega year". Prefixes are not usually used with a base unit of years. In most cases, the base unit is seconds or years. In other cases, the quantity name implies the base unit, like "century".

In some cases, the order of magnitude may be implied (usually 1), like a "second" or "year".

The model also ranked in the top 10 on NFLPickWatch four of the past six years on straight-up NFL picks and beat more than 94 percent of CBS Sports Football Pick'em players four times during that span. It is also on a 17-6 roll on top-rated NFL picks since Week 7 of last season. The model enters the 2023 NFL season on an incredible 163-113 run on top-rated NFL picks that dates back to the 2017 season. The model, which simulates every NFL game 10,000 times, is up over $7,000 for $100 players on top-rated NFL picks since its inception. All of the Week 2 NFL lines are listed below, and SportsLine's advanced computer model has all the NFL betting advice and predictions you need to make the best Week 2 NFL picks now. Detroit is a 4.5-point favorite in the latest Week 2 NFL odds.

However, before backing the Lions with your Week 2 NFL bets, you should also know that the Seahawks have both won and covered in the last three meetings between these teams. Detroit is 9-1 against the spread over its last 10, the best record in the league over that span. Seattle is 1-9 against the spread over its last 10 games, including the playoffs, and now heads to Detroit to face a Lions team with the inverse ATS record. There are a number of NFL betting trends that should be of high interest to anyone making Week 2 NFL picks.
