Year to Millisecond Converter

How to Convert Years to Milliseconds

To convert from years (yr) to milliseconds (ms), you multiply the number of years by 31,556,952,000. This is based on an average year length of 365 days, with 1 day having 86,400,000 milliseconds.

Formula

Milliseconds = Years × 31,556,952,000

or

ms = yr × 31,556,952,000

Step-by-step process

1. Take the measurement in years
2. Multiply that number by 31,556,952,000
3. The result is the equivalent time in milliseconds

Examples

• 1 yr = 1 × 31,556,952,000 = 31,556,952,000 ms
• 2 yr = 2 × 31,556,952,000 = 63,113,904,000 ms
