Online converters for values and formats

How to use the Hublabs converters

The converters turn a value from one format into another: currencies, units of measurement, dates, and number bases. Each page shows the rule used and an example to check.

Values are converted as you type. The currency converter uses reference rates and shows the date of the quote displayed.

They are useful for planning a trip, adapting a recipe that uses another country's measurements, understanding the date of a record stored as a number, or checking a hexadecimal value while studying programming.

Which converter to choose

• Currencies — to estimate amounts between Brazilian real, US dollar, euro, pound, and yen with a reference rate.
• Units — for length, mass, temperature, area, volume, time, and speed.
• Dates — to turn Unix timestamps into readable dates and dates into timestamps.
• Number bases — to see the same number in binary, octal, decimal, and hexadecimal.

Tips for converting without mistakes

• For units, choose the category first. You can only convert between units of the same kind, such as meters to kilometers or grams to kilograms.
• Unix timestamps can be in seconds or in milliseconds. Values with up to 10 digits are read as seconds; longer values, as milliseconds.
• When converting dates, check the time zone: the result is shown in your device's local time and also in UTC.
• For number bases, each base only accepts its own digits: 0 and 1 in binary, 0 to 7 in octal, and 0 to 9 plus the letters A to F in hexadecimal.

Reference rates do not include taxes or fees; confirm the final amount with your bank or card.
