Educational explanation
Kilohertz to megahertz
Convert kHz to MHz when an AM medium-wave channel plan, IF filter spec, or legacy radio dial lists kilohertz but an FM band table, RF front-end datasheet, or spectrum allocation chart quotes megahertz.
Both kilohertz and megahertz are SI frequency units anchored to hertz. On this catalog 1 MHz = 1000 kHz (Megahertz: 1e6, Kilohertz: 1000):
MHz = kHz ÷ 1000 · equivalently kHz = MHz × 1000
Step-by-step conversion (worked example — AM to FM scale)
Convert 1010 kHz AM channel to megahertz:
- 1010 ÷ 1000 = 1.01 MHz
- Note: FM stations sit near 88–108 MHz—different band, same unit ladder.
Second worked example (455 kHz IF)
- 455 ÷ 1000 = 0.455 MHz
Third worked example (1000 kHz anchor)
- 1000 ÷ 1000 = 1 MHz
Quick mental estimate
Drop three digits (divide by 10³) when moving kHz → MHz. Example: 1500 kHz → 1.5 MHz.
Kilohertz to megahertz conversion chart
| Kilohertz (kHz) | Megahertz (MHz) | Typical context |
|---|---|---|
| 1 kHz | 0.001 MHz | Audio / low-frequency anchor |
| 455 kHz | 0.455 MHz | Classic AM/FM IF frequency |
| 1000 kHz | 1 MHz | Definition step (1 MHz = 1000 kHz) |
| 1010 kHz | 1.01 MHz | AM broadcast example |
| 1500 kHz | 1.5 MHz | Shortwave / maritime band neighborhood |
| 27,000 kHz | 27 MHz | CB radio band (regional) |
Where kHz → MHz comes up
- Broadcast engineering: AM channel lists in kHz; FM and TV allocations in MHz.
- Receiver design: IF filters quoted in kHz; RF synthesizer in MHz.
- Spectrum compliance: Emission masks may mix kHz resolution with MHz band edges.
Megahertz to kilohertz
Convert MHz to kHz when an FM dial or RF module lists megahertz but a legacy IF filter datasheet or AM allocation table expects kilohertz.
kHz = MHz × 1000
Step-by-step conversion (worked example)
Convert 88.5 MHz FM center to kilohertz:
- 88.5 × 1000 = 88,500 kHz
Quick reference (MHz → kHz)
| Megahertz (MHz) | Kilohertz (kHz) | Typical context |
|---|---|---|
| 1 MHz | 1000 kHz | Anchor |
| 10 MHz | 10,000 kHz | Reference oscillator class |
| 88.5 MHz | 88,500 kHz | FM broadcast |
| 100 MHz | 100,000 kHz | RF test / scope bandwidth |
kHz vs Hz vs MHz ladder, and related tools
Three zeros separate each SI rung: Hz → kHz → MHz → GHz. Confirm band context before comparing channel numbers.
Common mistakes to avoid
- Confusing AM kHz channels with FM MHz channels—different services, same unit math.
- Off-by-three zeros between kHz and MHz.
- Mixing kHz with kbps—data rate, not frequency.

Frequently asked questions
What is the formula to convert kilohertz to megahertz?
MHz = kHz ÷ 1000. Example: 1010 kHz = 1.01 MHz.
What is the formula to convert megahertz to kilohertz?
kHz = MHz × 1000. Example: 88.5 MHz = 88,500 kHz.
How many kilohertz are in 1 megahertz?
Exactly 1000 kHz per MHz.
What is 455 kHz in megahertz?
0.455 MHz—a classic IF filter frequency.
What is 88.5 MHz in kilohertz?
88,500 kHz—FM broadcast band example.
Is the kHz-to-MHz conversion exact?
Yes—pure SI prefix math (10³ between kilo and mega).
Are AM and FM on the same MHz scale?
Both use frequency units, but AM medium-wave channels are typically labeled in kHz while FM uses MHz. Convert with ÷ 1000 when crossing labels.
How does kHz relate to Hz?
1 kHz = 1000 Hz. Use hertz-to-kilohertz when starting from base hertz.
How does MHz relate to GHz?
1 GHz = 1000 MHz. Use gigahertz-to-megahertz for the next rung up.
How do I validate a spreadsheet?
Convert 1010 kHz → 1.01 MHz → 1010 kHz round-trip.
