How it works
Both units measure time, so they are always in the same ratio: one hour equals 0.00011407946 years. The calculator multiplies the number of hours you type by 0.00011407946 to give years, and when you type into the years field it divides by the same factor to give hours. Because the ratio never changes, doubling the hours always doubles the years. Results are calculated at full precision and rounded only for display (up to eight decimal places, with very large or small values shown in scientific notation).
How to convert hours to years
- Write down the value in hours, for example 8,766 h.
- Multiply by the conversion factor 0.00011407946 (because 1 hour = 0.00011407946 year).
- 8,766 × 0.00011407946 = 1.0000205 year.
- To go back from years to hours, divide by 0.00011407946 – or multiply by 8,765.82.
