This page collects Figuro's everyday, practical calculators: dates and time, school grades, home-improvement materials, and small utilities like unit conversion and password generation. These are the tools for the questions that come up in daily life rather than a finance or math class — how many days until an event, how much gravel a driveway needs, or how strong a password really is.
Your exact age in years, months and days.
Difference between two dates.
The exact date a number of days, weeks or months out.
Add or subtract hours, minutes and seconds.
Total hours worked between a start and end time.
Weighted grade point average from your courses.
Final weighted grade from assignment scores.
Concrete volume needed for a slab.
Cubic yards, weight in tons, and bags needed for gravel, mulch, soil or stone.
Area of a room or space in square feet and square meters.
Number of steps and exact riser height for a staircase.
Network address, broadcast address and host range.
Strong random passwords with custom options.
Convert between common length and weight units.
Tip amount and per-person total for a bill.
A fun compatibility score between two names.
For anything involving dates, Age, Date, Days From Today, and Time all work with calendar math, but each answers a slightly different question — Age gives your current age from a birthdate, Date and Days From Today calculate spans or future dates, and Time and Hours handle clock-based durations.
For home and yard projects, Concrete, Gravel & Mulch, Square Footage, and Stair calculators are built around materials and measurements — enter your project's dimensions to get quantities or area, rather than a price (material costs vary too much by region to estimate reliably).
For school-related math, GPA and Grade calculators serve different purposes: GPA converts a full set of course grades and credit hours into a cumulative average, while Grade Calculator figures out what score you need on a remaining assignment or exam to hit a target overall grade.
For quick utilities, Conversion handles unit-to-unit math (length, weight, temperature, and more), Password Generator creates strong random passwords, and Subnet Calculator is a networking tool for figuring out IP ranges — useful for a very different audience than the rest of this category.
Do the home-project calculators (concrete, gravel, square footage) give me a cost estimate?
They calculate quantity and area — cubic yards of concrete or gravel, or square feet of a room — not price, since material costs vary widely by region and supplier. Use the quantity result to get an accurate quote from a local supplier.
What's the difference between the GPA Calculator and the Grade Calculator?
GPA Calculator looks backward: it takes grades you've already earned across multiple courses and computes your overall average. Grade Calculator looks forward: it tells you what score you still need on an upcoming assignment or final to reach a target grade.
How is Days From Today different from the Date Calculator?
Days From Today answers "what date is 45 days from now?" — a single direction, from today forward or backward. The Date Calculator is more general, finding the difference between any two dates you enter, not just from today.
Is the Password Generator's output actually secure?
It generates passwords using random character selection across the character sets you choose (letters, numbers, symbols), which is the standard approach for strong passwords. Length and character variety both matter — a longer password with mixed character types is meaningfully harder to crack.
Who is the Subnet Calculator actually for?
It's a networking utility for anyone configuring a local network or studying for a networking certification — it figures out IP address ranges, usable hosts, and subnet masks from a given address and prefix length.
