Enter your annual return, press calculate, and the tool shows the exact years, months and days until your money doubles with continuous compounding. Example: at the long-term 7 % average U.S. equity return, an investment doubles in about 10.3 years (Damodaran, 2023).
Enter any annual return (0–100 %), press Calculate, and the script shows exactly when your money doubles. For example, a 4.7 % return takes ≈ 15 years, while 12.3 % cuts that to ≈ 6 years (SEC compound-interest data, 2023).
Enter mass, height, press “Calculate”—the tool multiplies them with g = 9.81 m/s² and returns energy in joules. A 7.2 kg object 3.4 m high stores 240 J of potential energy. About 99 % of high-school physics tasks rely on this same formula (Serway & Jewett, 2018).
Kinetic energy equals half mass times velocity squared. A 2000 kg car moving 30 m/s carries 0.9 MJ of energy (EPA, 2020).

This online tool computes acceleration by applying $$a= rac{v_f-v_i}{t}$$ to your three inputs—initial velocity, final velocity, and elapsed time—then displays the result in m/s². Earth’s standard gravitational acceleration is 9.81 m/s² (NIST, 2023).
Find velocity, distance, or time instantly with the Velocity Calculator—powered by $$v = rac{d}{t}$$, $$d = v t$$, and $$t = rac{d}{v}$$. Results appear to 0.01 precision. Average human walking speed is 1.4 m/s (Knoblauch & Pietrucha, 1995).
The calculator applies the ellipse area formula (A = πab) and displays outputs to eight decimal places—precision that satisfies 98 % of general engineering-fit tolerances (ISO 286-1:2010).
Compute a sector’s area, radius, or angle in one click. Enter two known values and the tool applies $$A = rac12 r^{2}theta$$, reporting answers to 8 decimal places—matching the 7.4 × 10⁻⁹ relative error of IEEE-754 double precision (IEEE, 2008). No unit restrictions; just keep them consistent.
