Calculate Work, Power and Time
Online calculator and formulas for calculating work, power and time
Work, Power and Time Calculator
Power calculation
Calculates the relationship between Work (W), Power (P) and Time (t) according to the formula P = W / t.
Example Calculation & Time Formats
Example: Calculate power
Problem:
A machine performs 3,600 J of work in 2 minutes. What is the average power?
Given:
- Work W = 3,600 J
- Time t = 2 min = 120 s
- Find: Power P
Solution:
P = W / t
P = 3,600 J / 120 s
Time Input
Time is generally given in seconds. Alternatively, time can also be entered in hours, minutes and seconds. For this, a colon is used as a separator after the hours and an apostrophe after the minutes.
Time format examples:
2:14'10→ 2 hr, 14 min, 10 sec2:0→ 2 hr2:14→ 2 hr, 14 min
2:00'18→ 2 hr, 18 sec2'18→ 2 min, 18 sec3600→ 3600 seconds
Formulas for work, power and time
The units of measurement are Joule (J) for work, Watt (W) for power and seconds (s) for time.
Work from power and time
The work performed as the product of power and time.
Power from work and time
The average power as the quotient of work and time.
Time from work and power
The time required to perform a specific amount of work.
Important Notes
- Power describes the rate of energy conversion
- 1 Watt = 1 Joule per second = 1 kg·m²/s³
- With constant power, work is proportional to time
- Time can be specified in various formats
Detailed description of work, power and time
Physical Fundamentals
This function calculates the relationship between work, power and time. Power is defined as the work performed per unit time or energy converted. It describes how fast energy is converted.
Usage Instructions
To calculate, select which value should be calculated using the radio buttons. Then enter the required values and click the 'Calculate' button. Time can be entered both in seconds and in the format Hr:Min'Sec.
