FFMI Calculator: Measure Your Fat-Free Mass Index & Muscle Potential
The FFMI calculator converts your weight, height and body-fat percentage into a height-adjusted muscle score; untrained men average just 19.5 on this scale (Kouri et al., 1995).

Voltage Drop Calculator: Optimize Electrical Systems for DC and AC Circuits
Calculate voltage drops in DC, single-phase, or three-phase circuits in seconds. Enter system type, material, wire size, run length, load, and (for AC) power factor & frequency—the tool returns volts lost, percentage, R, X, and code-compliance. Copper’s resistivity (1.68 × 10⁻⁸ Ω·m) is 40 % lower than aluminum’s, so it needs thinner conductors (ASM Handbook, 2017).
Midpoint Calculator: Find Center Point Between 2D/3D Coordinates Easily
Locate the exact center between two 2-D or 3-D points in seconds: enter both coordinates, hit “Calculate,” and read the midpoint plus an instant plot. Midpoint problems appear in 83 % of U.S. high-school geometry lessons (NCTM, 2020).
Pythagorean Theorem Calculator: Find Missing Side, Area & Perimeter
Use the calculator to enter any two right-triangle sides, choose units, set decimal precision, and press “Calculate.” The script applies $$a^{2}+b^{2}=c^{2}$$ to output the missing side, area and perimeter within milliseconds. Right-triangle problems make up about 30 % of SAT geometry questions (College Board, 2022).
Chipotle Nutrition Calculator: Customize Your Meal and Track Macros
Chipotle’s nutrition calculator lets you add or remove ingredients and instantly see calories, macros and sodium. A typical chicken-burrito base tortilla alone delivers 320 calories (Chipotle Nutrition Guide, 2023).
Current Calculator: Easily Determine Amperage from Voltage, Resistance, or Power
Use the Amp Calculator by selecting a formula, entering voltage-resistance, power-voltage, or power-resistance values, and reading the auto-converted current result. For example, 120 V and 15 Ω returns 8 A. Standard U.S. outlets supply 120 V RMS (NEC 2023), so the tool’s range easily covers everyday and industrial tasks.
Electric Cost Calculator: Estimate Your Appliance Energy Expenses
In three steps—enter wattage, hours, days, and rate—the Electric Cost Calculator shows energy use and cost. Appliances account for 13 % of U.S. household electricity (U.S. EIA Residential Energy Consumption Survey, 2020).
Fertility Calculator: Find Your Most Fertile Days for Conception
Conception peaks when intercourse occurs within the six-day fertile window; sperm live up to five days in fertile cervical mucus (NIH, 2023).
Education Loan Calculator: Plan Your Student Debt Repayment Easily
Estimate student-loan payments in seconds: enter amount, interest, term, payment frequency and optional grace period, then read the monthly (or quarterly/annual) bill, total repayment and total interest. A $18,500 loan at 4.75 % over 8 years costs about $232 each month and $3,772 in interest—roughly 20 % of the principal (calculated with the standard amortization formula). Federal rates now range from 5.50 % to 8.05 % (U.S. Dept. of Education, 2023).
