About These Math & Misc Tools
Percentage Calculator
Our versatile Percentage Calculator simplifies all your percentage-based math problems. Whether you need to find 'what is X% of Y?', determine 'X is what percent of Y?', calculate the percentage increase or decrease between two values (e.g., for discounts or growth rates), or work backwards to find the original number when a percentage and partial value are known, this tool provides quick and accurate answers. It's perfect for everyday calculations, academic work, or financial analysis.
Average Calculator
Easily calculate the average (arithmetic mean) of any set of numbers with our Average Calculator. Input your numbers separated by commas, spaces, or new lines, and instantly get the mean value. Beyond the average, this tool also provides the total count of numbers entered, their sum, and identifies the minimum and maximum values within your dataset. Ideal for statistical analysis, grade averaging, or any scenario requiring a central tendency measure.
Grade Calculator
Determine your current weighted average grade in any course with our intuitive Grade Calculator. Input the grade (as a percentage) and the corresponding weight (also as a percentage) for each of your assignments, quizzes, exams, and other graded components. The calculator then computes your overall course grade, showing how each part contributes to your final standing. You can also use it to figure out what grade you need on a final assignment to achieve a target overall course grade.
GPA Calculator
Our GPA Calculator helps you accurately determine your Grade Point Average for a semester or cumulatively. Add your courses, select the letter grade received (e.g., A, B+, C-), and input the credit hours for each. The tool supports various GPA scales (like 4.0, 4.3, 4.5) and correctly handles Pass/No Pass grades by excluding them from the GPA calculation. It's an essential tool for students tracking their academic performance in high school or college.
Basic Unit Converter
This all-in-one Basic Unit Converter provides quick and easy conversions for a wide range of common measurements. Convert units for length (meters, feet, kilometers, miles), weight/mass (kilograms, pounds, ounces), temperature (Celsius, Fahrenheit, Kelvin), volume (liters, gallons, milliliters), speed (km/h, mph, m/s), area (square meters, square feet, acres), and data storage (MB, GB, KB). Simply select the conversion type, input your value, and choose your units for an instant result.
Random Number Generator
Generate one or multiple random numbers effortlessly with our Random Number Generator. Define your desired range by setting the minimum and maximum values (inclusive). You can also specify how many random numbers you need and choose whether to allow duplicates in the generated set. It's a perfect tool for games, contests, statistical sampling, or any situation requiring an unbiased random selection.
Ratio Calculator
Our Ratio Calculator makes it simple to solve for an unknown value 'x' in a proportion, typically expressed as 'a : b = c : x' or 'a/b = c/x'. Just input the three known values (a, b, and c), and the calculator will instantly find the missing value 'x' that keeps the ratios equivalent. This tool is useful for scaling recipes, map reading, financial calculations, or any math problem involving proportional relationships.
Character & Word Count
Get instant text statistics with our Character & Word Count tool. Whether you're writing an essay, a social media post, or a document, simply paste or type your text into the area. The calculator will immediately display the total character count (both with and without spaces), word count, sentence count (estimated based on common punctuation like periods, question marks, and exclamation points), and paragraph count (based on double line breaks). It's an essential utility for writers, editors, students, and anyone needing to track text length and structure.
