Watts to Heat Calculator
Compute heating time and required energy.
Instructions
Enter mass, specific heat, desired temperature rise, and heater power. The calculator outputs energy and time required.
Formula
Q = m c ΔT, t = Q / P
About Heating Time
Ideal estimate ignoring heat losses. Real systems take longer due to inefficiencies and environmental losses.
Common Questions
Is power constant?
This assumes constant power. Variable power requires integrating over time.
Can I input kW?
Convert to watts first (1 kW = 1000 W).
