Practice Problems
Problem 1:
Convert 500 A/m to mA/mm
Solution: 500 ÷ 1 = 500 mA/mm
Problem 2:
Convert 2.5 mA/mm to A/m
Solution: 2.5 × 1 = 2.5 A/m
Problem 3:
Convert 10000 μA/cm to A/m
Solution: 10000 × 0.0001 = 1 A/m
Problem 4:
Convert 0.1 kA/m to A/cm
Solution: (0.1 × 1000) ÷ 100 = 1 A/cm
Problem 5:
Convert 50 A/cm to mA/m
Solution: (50 × 100) ÷ 0.001 = 5,000,000 mA/m
