How to Calculate Scientific Units

What is Scientific Units?

A scientific unit converter handles SI unit conversions for energy (joules, eV, calories), pressure (Pa, atm, bar, mmHg), and other physical quantities used in research.

Formula

Energy: 1 calorie = 4.184 J; 1 eV = 1.602×10⁻¹⁹ J
J
1 — 1

Step-by-Step Guide

  1. 1Energy: 1 calorie = 4.184 J; 1 eV = 1.602×10⁻¹⁹ J
  2. 2Pressure: 1 atm = 101,325 Pa = 760 mmHg = 1.01325 bar
  3. 3Power: 1 horsepower = 745.7 W
  4. 4Force: 1 pound-force = 4.448 N

Worked Examples

Input
1 atmosphere in different units
Result
1 atm = 101,325 Pa = 760 mmHg = 1.01325 bar = 14.696 psi
