0.5 amps corresponds to 1800 coulombs of electric charge when flowing for one hour.
This is because electric charge (in coulombs) equals current (in amperes) multiplied by time (in seconds). Since 0.5 amps means half an ampere flowing continuously for a given time, multiplying it by the duration in seconds gives the total charge transferred.

Conversion Formula
The formula to convert amps (A) to charge (coulombs, C) is:
Charge (C) = Current (A) × Time (seconds)
This formula works because an ampere represents one coulomb of charge passing a point per second. So, multiplying the current by the duration in seconds gives the total charge moved.
Example for 0.5 amps flowing for 1 hour:
- Convert 1 hour to seconds: 1 hour × 3600 seconds/hour = 3600 seconds
- Multiply current by time: 0.5 A × 3600 s = 1800 C
- Result: 1800 coulombs of charge transferred in that hour
Conversion Example
- Example 1: 2 amps to charge over 1 hour
- Time in seconds = 1 × 3600 = 3600 s
- Charge = 2 A × 3600 s = 7200 C
- So, 2 amps transfers 7200 coulombs in one hour
- Example 2: 0.75 amps to charge over 30 minutes
- 30 minutes = 1800 seconds
- Charge = 0.75 A × 1800 s = 1350 C
- Therefore, 0.75 amps moves 1350 coulombs in half an hour
- Example 3: 1.5 amps to charge over 2 hours
- 2 hours = 7200 seconds
- Charge = 1.5 A × 7200 s = 10800 C
- This means 1.5 amps transfers 10800 coulombs in 2 hours
- Example 4: 0.25 amps to charge over 10 minutes
- 10 minutes = 600 seconds
- Charge = 0.25 A × 600 s = 150 C
- So, 0.25 amps gives 150 coulombs in ten minutes

Conversion Definitions
Amps: Amps, or amperes, is the unit measuring electric current. It quantifies how much electric charge passes a point in a circuit per second. One ampere equals one coulomb of charge flowing every second, indicating the rate of flow of electrons or charge carriers.
Charge: Charge is a physical property of matter expressed in coulombs. It represents the quantity of electricity carried by particles such as electrons or ions. Charge determines electromagnetic interaction, and one coulomb is the amount transferred by one ampere current in one second.
Conversion FAQs
Does the conversion from amps to charge depend on time?
Yes, the conversion requires knowing the time duration because amps measure rate of flow per second. Charge accumulates over time, so without specifying time, you cannot get total charge from amps alone.
What happens if the current is negative in amps?
A negative ampere value indicates the direction of current flow opposite to a defined reference. The charge value will also be negative, representing charge moving in reverse direction.
Can I convert amps to charge for less than one second?
Yes, just multiply the amps by the time interval in seconds, even if it’s a fraction. For example, 0.5 amps flowing for 0.1 seconds transfers 0.05 coulombs.
Is the charge always in coulombs when converting from amps?
When using standard SI units, yes, charge is expressed in coulombs. Other units exist, but coulombs are the standard unit in electrical calculations.
How accurate is the charge calculation from amps?
The calculation is accurate if current is constant and time measured precisely. Fluctuating current or imprecise timing can cause errors in total charge estimation.
