About this calculator

  2. Select the unit you are converting from and to.
  3. Press Convert to see the result.

Tips

  • "Month" and "year" use fixed approximations (30 days and 365 days) since calendar months and years vary in length — for exact calendar-date math, use a date calculator instead.
