Need to switch between milliseconds and centuries without breaking a sweat? This Time Unit Converter’s got your back. Just type a value—say, 3600000 milliseconds—and watch it transform into seconds, minutes, hours, days, weeks, months, years, decades, or even centuries right away. It’s built to save you from manual calculations or hunting down formulas, all wrapped in a clean, card-based grid that’s easy to read.

The tool handles a wide range of units, from the tiniest milliseconds to sprawling centuries. Conversions are based on solid formulas, ensuring accuracy every time—perfect for avoiding mistakes that could mess up your plans. Note that months (30.44 days), years (365.25 days), decades, and centuries are approximate, accounting for leap years and such, but it’s reliable for most tasks.

Give it a try—throw in a random value like 86400 seconds and see how it breaks down into a day’s worth of time units.

Getting started is a breeze. Pick your starting unit from the dropdown, enter your number, and the grid fills in the rest instantly. Messed up? Hit the “Reset” button to clear it all and start fresh. The layout’s intuitive, with a smooth blue gradient background that doesn’t distract, making it a snap to compare values side by side.
