Definitions and assumptions

Time factors are expressed relative to seconds. For approximate duration conversion, one year is 365.25 days and one month is one twelfth of that year. Calendar months and date intervals can have different lengths.

Frequently asked questions

Which Time units are supported?

The directory lists 10 units, including symbols and availability. Choose any source unit to browse its target units.

how to convert h to min?

The calculator converts the input to the category's reference unit, then divides by the target unit's factor. 1 × 60 ≈ 60 Minutes. Use the source and target factors shown in the formula. The worked example uses the value on this page, and the table provides other common values.

Does one month always equal the duration shown here?

No. This is an average-duration convention. Use actual calendar dates when the number of days in a particular month or year matters.

Why is the displayed result rounded?

Auto mode preserves significant digits for small values; manual mode rounds to the selected decimal places. ≈ means approximate; < means below the display limit. Extreme values use × 10ⁿ. Calculations are rounded only for display.

What input range can I use?

This calculator accepts non-negative values up to 1 trillion, with up to 8 decimal places. It does not calculate signed vectors or calendar date intervals.

Why is a unit unavailable?

A conversion is unavailable when a verified unit definition or a current exchange-rate value has not been configured. The tool does not invent a coefficient.
