Age Calculator
Months are not a fixed length, so dividing days by 365.25 gives a different answer from the calendar. This uses the calendar method every official form uses.
Time📏Celsius to Fahrenheit
All four scales at once, with the offset handled correctly — plus the trap that catches everyone: converting a temperature difference is not the same as converting a temperature.
Converters📏Cups to mL
“One cup” is five different volumes depending on where the recipe was written. Pick the right one, and find out why an Australian tablespoon will ruin your scones.
Converters🕑Date Calculator
Days are exact. Months clamp to the end of a shorter month and never come back, which is why monthly billing drifts after its first February.
Time🕑Days Between Dates
Total days, working days, weekends and the exact years-months-days breakdown — plus the answer to whether the count should include the end date, which is where people differ.
Time📏Feet to cm
Type 5'11", 5 ft 11, 5-11 or 71 in — it reads all of them. Built for height, with the rounding traps that make passports and medical forms disagree.
Converters📏kg to Pounds
Reads and writes British weight the way people actually say it — 11 st 4 lb, not 11.29 stone. Handles the fourteen-pound boundary that trips up mental arithmetic.
Converters📏Oven Temperature Converter
Includes the fan-oven adjustment almost every chart leaves out — the 20°C that explains why your bakes brown too fast and dry out in the middle.
Converters📊Percentage Change
Four related questions in one place — change between two numbers, apply a percentage, find the original, and see the working written out so you can check it.
Math📊Progress ETA
A progress bar extrapolates from the last instant. Measuring over a longer window is the whole reason a manual estimate is better.
Math💰Split the Bill
100 divided by three is 33.33 each, which totals 99.99. This hands out the leftover pennies so the parts match the bill exactly.
Finance🕑Stopwatch & Timer
Counting setInterval ticks loses time on every late fire. This reads the clock instead, so it stays accurate even when the tab is throttled.
Time📏Unit Converter
Length, mass, volume, area, speed and temperature — with the units that share a name listed separately instead of silently picked for you.
Converters🛒Unit Price Compare
It happens often enough to have a name — the quantity surcharge. Convert everything to one unit and the shelf stops being able to hide it.
