# Years to microseconds

**1 year in microseconds: 1 yr = 31,556,952,000,000 µs**

µs = yr × 31,556,952,000,000

To convert years to microseconds, multiply by 31,556,952,000,000. The table below gives the values people look up most often, and the converter works for any number.

## How the conversion works

The relationship is µs = yr × 31,556,952,000,000. Both units measure time, so the conversion is a fixed factor that never changes.

> Year: Mean Gregorian year, 365.2425 days.

## Common questions

### How many microseconds are in one year?

One year equals 31,556,952,000,000 microseconds. µs = yr × 31,556,952,000,000.

### How do you convert years to microseconds?

Use µs = yr × 31,556,952,000,000. So 10 yr is 315,569,520,000,000 µs.

### How many years are in one microsecond?

One microsecond equals 3.169 × 10^-14 years, which is the reverse of the conversion above.

### Is there more than one kind of year?

Mean Gregorian year, 365.2425 days.
