The tool converts a nominal rate and compounding frequency into Annual Percentage Yield (APY) so you know the real yearly return on savings. For example, a 6 % rate compounded daily yields 6.18 % APY—0.18 percentage point more than annual compounding (Investopedia, 2024).
Estimate angle-iron weight in seconds: fill in leg sizes, length, thickness and material density, then hit “Calculate.” The tool multiplies each leg’s volume by the density and sums them—standard steel density is 0.284 lb/in³ (MatWeb, 2023). Ideal for quick take-offs and load checks.
The calculator counts the exact days between any date and today by dividing the millisecond gap by the 86 400 seconds that make up a day (NIST, 2023). Use it to see how long ago an event happened or how many days remain until a deadline—instantly, in your browser.
Input two points to instantly see their midpoint, distance and the missing endpoint. The midpoint averages the coordinates, the distance applies the Pythagorean theorem, and the unknown endpoint doubles the midpoint then subtracts the known endpoint. Midpoint and distance skills appear in 100 % of the Common Core high-school geometry standards (Common Core State Standards, 2010).
The BMI calculator turns your pounds-and-inches data into metric units and divides weight (kg) by height² (m²) to reveal whether you are under-, normal-, over-weight or obese. About 74 % of U.S. men fall into the overweight or obese brackets (CDC, 2023).
Convert CMYK print percentages to screen-ready RGB in three steps. Enter four 0–100 % numbers, hit convert, and get 0–255 RGB plus Hex. Each RGB channel supports 256 discrete levels (0–255) (ITU-R BT.709, 2022).
Use the calculator by entering an annual rate (e.g., 7 %), the number of days (e.g., 540), and the future value (e.g., $12 500); the tool instantly returns the discount factor and present value. A 1 % change in the rate moves present value by roughly 0.9 % for one-year cash flows (Federal Reserve, 2023).
Click once and learn whether today is an official public holiday in your country. The checker identifies your location via IP, queries the Nager.Date API, and returns a colour-coded answer. The average nation designates 11 statutory public holidays each year (ILO Working-Time Report, 2021).
Convert any calendar date to a Unix timestamp in seconds. Enter year, month, day, hour, minute and second, pick UTC or local, press Convert—your result appears instantly. Unix time starts at 00:00:00 UTC on 1 Jan 1970 and has powered operating systems for over 50 years, recording more than 1.7 billion seconds so far (POSIX Epoch Counter, 2024). [IEEE Std 1003.1-2017]
