You in Every Unit
Type your height, weight and age — and see yourself measured in heartbeats, nanoseconds, megatons and atoms.
Your numbers
Your body as pure energy (E = mc²)
93,083Hiroshima bombs
If your body's mass became energy, it would equal this many Hiroshima bombs.
You in Time
Heartbeats
1,104,516,000beats
Your heart has beaten about 1,104,516,000 times so far.
Breaths
236,682,000breaths
That's how many times you've breathed in and out.
Seconds alive
9.47×10⁸s
You've been alive for about 946,728,000 seconds.
Time asleep
10years
About 87,660 hours — roughly 3,653 days of sleep.
Trips around the Sun
30orbits
You've ridden Earth all the way around its orbit this many times.
Full moons seen
371full moons
That many full moons have risen since you were born.
You in Size
Your height
1,700mm
That's 66.9 inches tall.
Light crosses you in
5.67ns
Light travels your whole height in just 5.67 nanoseconds.
Body surface area
1.75m²
The total skin wrapping your body (Mosteller formula).
You to the Burj Khalifa
487of you
Stack 487 of you to reach the top of the world's tallest building.
You to Everest's summit
5,205of you
It would take 5,205 of you stacked head-to-toe to reach the top of Everest.
You in Mass-Energy
Your weight on the Moon
10.8kg
You'd weigh just 10.8 kg on the Moon.
Your weight on Mars
24.5kg
On Mars you'd tip the scales at 24.5 kg.
Your weight on Jupiter
164.5kg
Jupiter's gravity would make you weigh 164.5 kg.
Water in your body
39L
About 60% of you is water.
Inside You
Heat you give off
78W
At rest you glow like a 78-watt light bulb.
Blood in your body
4.6L
Roughly 70 mL of blood for every kilogram of you.
Atoms in your body
6.50×10²⁷atoms
Forged in stars long before you were born.
DNA data per cell
1.5GB
Your genome fits in about 1.5 GB — smaller than a movie.
All figures are estimates from average rates and your entered numbers (no clock is used). Real values vary by person, fitness and age.
Body-surface area from the Mosteller (1987) formula. Surface-gravity ratios from the NASA Planetary Fact Sheet. Genome size ≈ 1.5 GB per cell (diploid, 2-bit encoding). Heart rate ≈ 70 bpm, breathing ≈ 15/min, and ~1/3 of life asleep are population averages.
