# Light-years to Yards (ly to yd)

Source: https://www.unitconvertercalculator.com/length/light-years-to-yards/

**1 ly = 1.0346380656803E+16 yd**

One light-year equals approximately 1.035 x 1016 yards (about 10.3 quadrillion). The light-year measures stellar distances; the yard measures sports fields and fabric. Light travels about 327,857 yards per millisecond.

## Units

### Light-year (ly)

The distance light travels in one Julian year (365.25 days) in vacuum. Exactly 9,460,730,472,580,800 meters. Used for interstellar distances.

### Yard (yd)

An imperial unit of length equal to 3 feet or 0.9144 meters. Used in American football, golf, and fabric measurement.

## Background

Proxima Centauri at 4.24 light-years is about 4.387 x 1016 yards away (43.9 quadrillion). A 100-yard football field is 9.66 x 10-15 light-years. The entire NFL season produces far less total yardage than a photon covers in a second.

## Good to Know

The yard measures American sports. The light-year measures the universe those sports exist in. Every touchdown pass (40-70 yards) crosses about 4 x 10-14 light-years of space. Football is cosmically insignificant. Fans disagree.

## FAQ

### How many yards are in 1 light-year?

One light-year contains approximately 1.035 x 1016 yards (about 10.3 quadrillion).

### How fast does light travel in yards?

Light travels approximately 327,857,019 yards per second (about 328 million yards/s).

### Is this conversion used?

Only as a fun fact. Light covers about 328 million yards per second, or 3.28 million football fields per second.

## Non-Frequently Asked Questions

### How many football fields per second does light travel?

Light crosses about 3.28 million football fields per second. An NFL broadcast covering a play takes about 5 seconds. In that time, light has crossed 16.4 million football fields. The universe moves faster than the broadcast.

### How many yards has the NFL produced in total?

Over 100+ seasons, the NFL has produced roughly 30-40 million total offensive yards. One light-year is 10.35 quadrillion yards. All NFL yardage in history is about 3.9 x 10-9 light-years. The NFL has not yet produced enough yardage to matter cosmically.

### If a bolt of fabric were 1 light-year long, how much would it cost?

A bolt of fabric costs about $5 per yard. One light-year (1.035 x 1016 yards) would cost about $51.7 quadrillion. Global GDP is about $100 trillion. A light-year of fabric costs 517 times more than everything the world produces in a year. Fashion is expensive.
