Formula
1 M = 10⁶
About this calculator
The Mega (M) → base converter transforms values with the SI prefix 'Mega' into their base unit. The prefix Mega stands for 10⁶ (1 million), meaning 1 M = 1,000,000. Simply input the value in Mega, and the tool will multiply it by 1,000,000 automatically. Example: 5 M = 5,000,000.
This tool is practical in science, engineering, and technology where large numbers are common. For instance, in electronics, a 2 MΩ resistor equals 2,000,000 Ω. It also works for data units like 1 MB = 1,000,000 bytes (in SI contexts).
Warning: In computing, 'Mega' sometimes refers to 2²⁰ (1,048,576) in binary systems. Check the measurement context before using this converter. Never confuse Mega (SI) with Mebi (2²⁰), which is used in digital storage.
Frequently asked questions
What is the Mega prefix?
Mega is an SI prefix representing 10⁶ (1 million). Example: 1 Mm = 1,000,000 meters.
How does the conversion work?
Multiply the Mega value by 1,000,000. Example: 3 M = 3 × 1,000,000 = 3,000,000.
When to use this converter?
Use it with physical units, electronics, or data in SI contexts. Example: 2 MB = 2,000,000 bytes.
Is Mega the same as Mebi?
No, Mebi (Mi) is 2²⁰ = 1,048,576 used in digital storage. Mega (SI) is always 1,000,000.
